[@DaWobble]

The cabbage water acts as a universal indicator (tells us whether a substance is an acid neutral or alkali). So the reason why the water goes red for the lemon and vinegar is because they are acids. Acids are usually yellow, orange or red and red being the strongest and yellow the weakest. This means the lemon and vinegar solutions are very acidic. As for the baking soda and ammonia, they are both alkali so they got blue, dark blue or violet. Violet being the strongest and blue being the weakest. The ammonia was a weak alkali because it was a dark green on its own. Green mean that the solution is neutralised meaning it's neither acidic or alkali. 👍

[@RomanNumural9]

The cabbage juice works as an acid base indicator. Basically depending on what the cabbage juice is mixed with, the chemical structure will change in such a way that it absorbs light differently. Acidic things such as vinegar (dilute acetic acid) or lemon juice (citrus) will donate a proton and cause the cabbage juice to turn red. basic things like hydrogen carbonate (baking soda) or ammonia (NH3) will accept a proton from the cabbage, which makes it appear a 'colder' colour like blue or green based on the extent of the reaction. I don't know the exact chemistry behind why the baking soda turns it green and the ammonia turns it blue, but the cabbage juice is probably polyprotic (can accept more than one proton). This means it could potentially change colours twice and thus go from purple to green to blue. That would be my reasoning.

[@ceilingfan7505]

Cool.

[@oursole2918]

+Josh McGillivray pretty sure the green color indicates neutrality (Equal concentrations of H+ and OH- ions). I could be wrong though. it DID go blue-ish green though, so it could be closer to basic than acidic.

In German there a two words for cabbage "Rotkohl" (red cabbage) and "Blaukraut" (blue cabbage). So there are 185.000 chemists from their very first beginnings. Think about that!

[@randomdude4628]

Cabbage has a chemical in it that works as a pH indicator. When you add in a base, it reacts in equilibrium with the OH- group from the dissociated base, and when you add an acid, it reacts with the H+ ion from the dissociated acid. Then, when you have the base in, and add an acid, the base reacts with the acid which shifts the equilibrium between the base and the indicator and causes a colour change.

[@marco_evertus]

it changes color based on the pH of the solution just like litmus paper. if the solution is acidic it turns red and basic it turns blue

The red cabbage has a universal indicator that changes colors with the acidity. Red with acids like vinegar and lemon juice and other colors with the alkaline baking soda and ammonia Awesome video

[@alya7800]

cabbage is a "acid-base indicator" and when you mix it with ammonia which is a base it turns purple or dark blue, it means ammonia is a strong base. whereas baking soda turns green because it's a weak base. and when you mix lemon with it it turns red and it means lemon is an acid. when the indicator color change it shows you whether it's a base or acid or whether it's weak or strong.

[@agent475816]

The red cabbage has a chemical in it called flavin. It is a pH indicator. A pH indicator changes color with changing concentrations of hydronium ions (H30+). Making the solution basic, turns it a darker green/blue color while making the solution acidic, turns it red. This molecule can be used for pH titration where the concentration for an unknown base is calculated by adding acid and vice versa. Both the lemon juice and vinegar (acetic acid) were acids which turned the color red. The ammonia and baking soda were basic which turned it green/blue.

[@ioanabalan9]

The cabbage juice is an universal pH indicator. All the liquids you used had different acidity levels which, in cabbage juice, change colour. Vinegar is a 1-2 on the pH scale (look that up if you don't know). If it has a low number, it is highly acidic. It also changes to a reddish, yellowish or orangish colour. The ammonia is alkaline. It has a higher pH number (10-11) so it turns blue/green. It is an easy experiment which i personally did in year 7. It is all about that cabbage juice. :)

[@NeverBeBored08]

It probably has something to do with the compounds left from the cabbage. Since both vinegar and lemon juice are acidic, it would make sense that both solutions turned red when reacted with acid. Since both ammonia and baking soda are basic, they turned similar darker colors. It's almost like litmus paper.

[@ElleDeas]

Alright, now THIS was interesting and pretty! Honestly, the purple color the cabbage produced (heh) was a beauuuuuuutiful purple.

[@GoddessAstrola]

Taras you asked for an explanation as to why it does this so here goes. Now if I'm not mistaken the the pigments from the cabbage are reacting to the PH of the water by adding acids (lemon juice, vinegar, and ammonia) or a base (baking soda) provides the reaction that lets the cabbage water to act almost like litmus paper just more wet.

[@maureendooley]

It's because of the Ph scale. I did this experiment, and it's based of acids, bases, and neutrals. For example, an acid, like lemon juice will be a more vibrant color, and you match that color with the one on the ph scale and you can tell if it's an acid base or neutral

[@Alhameiri991]

i have already studied this and made a project about it, it changes colour because when you are pouring the solutions its changing the acidity and basicity of the cabbage solution.

[@jacobgoodman9392]

CRH is seriously one of the coolest guys on KZbin.

[@AnarchistMetalhead]

"as you can see you can do a lot of different things and end up with different results" thank you, hacker

[@masonite1]

Red cabbage juice is a PH indicator. Just like litmus paper it will change colors due to the concentration of either an acid or a base. Acids, when mixed with an indicator , will turn all warm colors such as red , orange, and yellow depending on the concentration. Bases will change to cool colors such as blue, green, and purple . The PH scale is a scale used by chemists to determine the concentration of a solution. The scale is from 1 , being most acidic , to 14 , mostly basic. 7 is a middle range so completely distilled water is a 7 on the PH scale

[@leigh7729]

Because cabbage is a kind of universal indicator, which - depending on what colour it changes - tells you the pH level of the substance you add to it, for example lemon juice is a strong acid, so it will turn it red, and water is neutral, so it will turn it green (neutral is pH 7) but depending on how much acid/alkali you mix into the water, it will be either a different shade of green, or look like green mixed with another colour. Strong acids will be red/dark orange Weak acids will be orange/yellow Neutral will be green Weak alkalis will be blues Stronger alkalis will be purple Strong alkalis will be pink (I think) So, pH 1 = red, pH2 = lighter red pH3 = dark orange pH4 = orange pH5 = light orange pH6 = yellow pH7 = green pH8 = light blue pH9 = blue pH10 = dark blue pH11 = purple pH12 = lighter purple (I think) and pH13 = pinky purple I think I'd make a pretty good science teacher

[@nowandaround312]

The cabbage water has something in it called a flavin, and this acts as an indicator which tells you the pH of the solution. pH means where something falls on the acid-base scale. For example, battery acid is close to 0. The color it changes to depends on the pH of what you're adding. Acids like lemon juice change to orange/red and bases like ammonia change it to blue-green. Purple is the color when the pH is neutral and that is why it changes back. You added an acid or a base first and then when you poured in the opposite it brought the pH back to neutral so it returned to purple.

[@edgrtuck3r]

The reason the water turned different colors has to do with acids and bases. The cabbage water is an indicator. If the mixture added to it is acidic, the water will turn a shade of red; the intensity of that red depends on how acidic the mixture is. Lemon juice and vinegar are both acidic, hence the color of the cabbage water turning red. If a mixture added to the cabbage water is neutral/basic (such as water) is added to it, the liquid will turn a deep green. Ammonia is a neutral liquid, hence the color of the cabbage water turning green. If the mixture added to the cabbage water is a base, such as the baking soda/water mixture used in this video, the color of the indicator (cabbage water in this case) will turn a shade of blue; the intensity of that blue depends on the base you add to the indicator. Your welcome.

[@tomward9652]

The reason the mixture changes colour is because it's a universal indicator. That means it can detect the Ph scale (how acidic or alkaline it is) and if it's green, it means it's quite alkaline. If it's red, it's quite acidic

[@areamusicale]

I try to guess, lemon and vinegar are acid and react with the spectrum below the PH7 ( which is neutral), the ammonia and soda are bases, so if compared to the colour that appears in the litmus paper, that will be the opposite. The cabbage organic material reacts in a similar way of the litmus paper.... I guess.

[@foodlover...95]

the cabbage juice is a sort of universal indicator. so if u pour it onto a acid it will turn red,orange or yellow depending on how strong it is. If u pour it and it turns green it means it is neutral. if u pour it and it turns blue or purple it means its a alkali

[@kylepoole9472]

Acid and Alkaline liquids. The cabbage water is essentially a universal indicator which changes to a colour on the scake of Red to Purple depending in the Acid or Alkaline content

[@keon5721]

The cabbage juice is basic, and the vinegar and lemon juice are acidic. The acidic liquids turn warm colors like yellow, red, and orange. The basic liquids turn cool colors like purple, blue, and green.

[@zieverinkpatrick]

it is a pH indicator it'll switch to red if the pH is low (e.g. 3), to blue if it is high (e.g. 12), green is in between the switching.

[@cartienthusiast5115]

It's like a universal indicator. But from cabbages. It measures the pH level of any liquid you mix it with. Exactly what universal indicator does. However universal indicator request around 2 or 3 drops to show pH level. Not as much as cabbage.

[@jagroopbajwa6175]

this would be an awesome prank, hey bro want grape juice?

[@micahphilson]

I forget the major compound in purple cabbage that does that, but it's the same principle as pH paper. The acids were red and the bases were blue and green.

[@hassanmoussawi6688]

the red cabbage water is also used as a acid base nutrel solutions so if you mix cabbage water with acidic solutions like lemons and vinegar it will turn red and if you put cabbage water on base solutions like amonia and household detergents it will turn green and if you add cabbage water on nutrel substances or solution then the color will not change like water or sodium bicarbonate but the cabbage water would become more lighter but that doesnt matter either its red or green or purple and blue

[@joshsaskin6200]

The cabbage has a pH or pOH indicator (most likely iodine). When an acidic compound is added (citric acid/acetic acid) it shifts to red, however when a base is added (ammonia/sodium bicarbonate) it will shift towards the blue side of the pH scale.

[@rossorourke201]

The Red cabbage juice is an indicator which can show the Ph (level of acid/alkaline) by colour. Vinegar was a strong acid so it was red. Amonia was green because it was a very strong alkaline. baking soda was a medium alkaline. lemon was a strong enough acid. (I don't know the exact level of Ph for each)

[@Aksel27]

It has to do with the pH+ of the solutes. The lemon and vinegar are acidic, so they turn it red or pink. The baking soda and ammonia are basic, so they turn it blue or green.

[@shopmedia_]

cabbage is a universal indicator for the pH scale of chemicals. red is an acid with a pH of around 4 or below. blue is an alkali with a pH of around 10 or above

[@jaredmiller2714]

It changes because of the pH levels in the chemicals like the vinegar is an acid so it will turn red and baking soda is a base so it turns green and if it's strong enough it will turn yellow

[@Eagezz]

Red cabbage can act as a pH indicator, and since the items you used were either a base or an acid, the color of the water changed.

[@Kungfumaster27]

Cabbage juice is used as a pH level meter/detector so acids turn red or orangish and bases turn green or bluish depending on how acidic or basic the substance is

[@estidi]

I remember doing this in high school for lab experiment. Of course we didn't use cabbage extract, but some kind of chemical liquid that I forgot the name. Although my chemistry teacher did say that we could substitute it with cabbage extract.

[@bhavnasheth8343]

The lemon and vinegar are acids, the ammonia is not too acidic and not too alkaline so therefore neutral and the baking soda solution is alkaline and turned the water blue.

[@Mohammed-6-6-6]

Instructions unclear, nuclear missile launched.

[@peachynamosa]

The Vinegar & lemon juice turned Red because their pH acidic, the ammonia turned Green because it's pH is Neutral & the baking soda turned Blue because it's pH is Alkaline (Basic) .. Throwback to year 8/9 Science :')

[@samihattab9567]

I have to admit that was actually cool

[@jacobsolt8263]

this is basically just measuring the PH of the liquids ammonia turns it green because it's really basic and vinegar/lemons turn it more red because they are acids

[@Imacuser223]

Red cabbage water is a _pH indicator_. It turns red in the presence of acids and from blue to green to yellow when a base is added.

[@lewiscritchley3474]

Because you can use cabbage as a universal indicator so acids go red, neutral is green, alkali is blue/purple. Google pH scale

[@juana6029]

It changed color because cabbage juice is a pH indicator. pH is used to measure things' acidity. Yellow or green is near 7 pH. 7 pH is between acid and basic substances. Water has a pH of 7. Red, Orange and Yellow is below 7, that means its an acid substance. If it's over 7, it will be green,blue or purple. That's basicity.

[@camblackburn9830]

Since the red cabbage is a indicator for acids and alkalis and on the pH scale vinegar and lemon juice are acidic so they turn a red colour as for the others they are alkaline so they turn either purple or blue depending on the strength ;)

[@camblackburn9830]

I'm now studying this for chemisty

[@arikas_designs23]

It changes because of the different substances and the color prism can bend light so when you mix them it changes color to your eye.

[@otsokivivuori7726]

pH value of the chemical put in the gabbage juice determines the color. 6 or less is red or reddish, 8 or more is green or greenish, and 7 is blue.

[@joepal45]

It changes colour because the cabbage acts as a indicator for acid and alkali so when acidic things like lemon and vinegar it will change to red but when you add alkali things like baking soda it will change purple

[@thomaskilada2544]

it changes color because of the acidity and base of the liquid pored in. For example vinegar is a acid and on a pH scale it would turn red. And baking soda is a base and on a pH scale it would turn blue.

[@3dgamersrule468]

the red cabbage goes different colours when you add things because it will go red/pink/orange with an acid and blue/purple with alkilis it will depend on the strength of the acid/alkili red cabbage can be used as an indicator for the PH level

[@Carlito_MD]

If this guy would take a chemistry class he would love it (and be able to explain this so that the video actually teaches something..)

[@jacobriggs8938]

boiling the cabbage creates a reactive dye called an indicator that changes colors to different pH levels (red-acid, blue-base, green-buffer)

[@kantarro671]

each substance has different acidity. venigar and lemon are acid so they turn red. Baking soda and ammonia are bases so they turn blue. cabage juice is a pH indicator

[@katelynfe]

this is basically like those papers that you test the PH levels on. red=acid blue=base. ammonia is a weak base so it turned a greenish blue.

[@nathanaelsadgrove]

Cabbage juice is a type of indicator. When this type of indicator meets an acid it turns red, and when it meets an alkaline it turns green/blue.

[@freshblaze5222]

The cabbage Is a universal indicator. If you add an acid, it will go red. If you add an alkali, it will go purple. If it is neutral, it will go green. On the ph scale acid is red, neutral is green and alkali is blue.

[@isaireyes-quiroz9032]

That's the PH scale. The reds are acids, the green and blues are bases. The cabbage juice helps find out what's acidic or basic

[@t1ssy131]

I love it when chemicals change the colour of liquids (I mainly like the colours though!!!!!)

[@DanielRCaceres]

Cabbage "juice" is offen used as ph indicator, when it turns red or orange is something with acid ph, when it turns blue or green is a base. :)

[@brianoconnor8479]

It's a natural pH balance scale. sp the acidic stuff turns it red. the base stuff turns it into green/blue

[@shrimatkapoor2200]

It changed colours because of its pH scale. The more acidic the solution the redder/orange the colour. However, alkali solutions turn the mixture blue/dark green or purple.

[@anisa3280]

Because cabbage "juice" is a universal indicator and so if you mix it with liquids it will show how alkaline or acidic it is (according to the colours on the ph scale)

[@BadgerGamePlay]

Red cabbage contains a pigment molecule called flavin. in simple terms a chemical that changes colors when introduced with an acid or alkali (indicator). color red is represents acid; the deeper the color the stronger the acid. same goes for alkali however its color is purple. if its green it means its neutral. (look up PH scales if you want to :D)

[@BadgerGamePlay]

i just explained to people who dont know it :P

[@ertz141]

Alkali are indicated with the colour blue, not purple

[@BadgerGamePlay]

its purple bro, type in ph color scale :P it maybe blue on some other indicators, there is more then one

[@idklol1]

ThatOneChannel purple is strong alkali like sodium hydroxide blue is weak alkali like milk.

[@mikewest3108]

It must be the pH of the various solutions. It turned red each time you added acid in the form of vinegar which contains acetic acid and lemon which contains citric acid (both have a pH of about 2) and blue for ammonia ( pH 11) And the baking soda solution which turned the color green has a pH 9 which is not as high as the ammonia. The color seemed to revert back when you altered the pH of the acids by adding ammonia to them.

[@nadaalsarraf3452]

this happens because cabbage water is an indicator for acids and bases so when you add venigar and lemon which are acids it turns red while ammonia and baking soda are bases which turn blue but baking soda turned green because it is a weak base while ammonia is a strong base

[@dazzamarin9417]

Chemical change, cabbage is used like a pH scale. The pink is acidic and green is nuetral and blue was basic

[@TESTACCOUNT-5]

cabbage is an indicator for the acidity level of a liquid. If the cabbage turns red it is an acid, if it is green-ish it is in between AKA neutral, if it turns blue it turns into an alkali which is the opposite of acid. =D

[@idklol1]

acidity level? no, the pH m8.

[@SillySausagejj106ful]

They change colours because they are either basic or acidic, basic solutions, such as the baking soda and the ammonia they turn deep dark colours, the acidic solutions, such as vinegar and the lemon juice they turn a bright colour. Cabbage juice is on of many ph indicators. you can also use universal indicator or methyal orange or litmus to determine what pg the solution is.

[@SillySausagejj106ful]

ph*

[@quemarsazizi1163]

There's a level of colors on the ph scale and its from 0-14 and there are acidic neutral and basic. Cabbage juice is an indicator for those

[@jaseb485]

BOOM! I think i learned this in elementary school, about 25+ years ago.

[@pigeonsmoker8770]

When red cabbage is boiled and made into that purple juice it is like a ph decetor and or litmus strip that shows how basic or acidic the object is lemon is acidic it turned red while baking soda is basic and it turned blue thats why it changes colour

[@khawlaha3399]

Lemon and Vinegar are both acids and they showed quite a similar effect of color change. Baking Soda and Clear Ammonia are both alkaline and showed a different color change effect.. green and blue Could you repeat the experiment, but with using same amounts of each of the 4 liquids and same amount of cabbage water,however, taking care to take cabbage water samples at close time intervals

[@Boss-xr7kh]

That's so crazy!!!! I love your videos!!! Awesome CHANNEL!!!

[@bozofilmz8839]

It changes because cabbage has a PH sensitive properties that allows it to change color depending on PH, Purple is very Basic, Red and Pink are very acidic.

[@beccaran]

Cabbage juice is a universal indicator (meaning that it can indicate the presence of both acids and bases by a change in colour)

[@ellamackenzie6328]

I did this in science, the red cabbage solution is an indicator so when you either put an acid or alkali in the mixture it will change colour to show if the substance mixed in is acid or alkali....

[@Premises225]

I actually did this in science about 3 years ago it basically shows you how acidic things are

[@FLIPkicks]

When red cabbage juice is mixed with an acid, base, or neutral, it turns the different colors.
