Turning copper into 'silver' and 'gold'

[@TheOtherSteel]

We've turned it into silver, but not really. Then we've turned it into gold, but not really.

[@ShoumanBaruaShuvo]

I agree. :p

[@muhammadalihafeezyousuf107]

TheOtherSteel what r the ingredients plz tell

[@TheWartitan]

What did you expect? Alchemy? ^^

[@Analyst8x23]

It is not really sliver or gold, its a zinc and brass layering it just looks like gold and sliver. Could you imagine how worthless gold and sliver would be if you could create it this easily. (btw if you listened carefully she told already told you)

[@Heartothetube]

Thank you so MUCH for the brain behind this science that was so well performed and explained.

[@Ammondn]

This blew my mind to see zinc plate out onto copper! Usually it's the other way around. I purify precious metals for a living and this one caught me off guard. I also didn't expect zinc to dissolve in strong base. Keep sending cool videos like this one!!

[@badendhappy2903]

Isn't it bad practice to leave the Bunsen burner on?

[@wzukr]

Found this channel at least today! Subscribed immedialy, my daughter will love it too. Mcu better way to learn chemistry then in school ;-)

[@alichaudhry345]

So in the End, we Really can't get rich!!???

[@riziwan1000]

in my point of view we should first make a powder with some salt of zinc then make a reaction or

[@55569659]

please tel me sir/ medam ,how to convert copper into iridium OR Turning copper into iridium

[@jaystern5936]

Glad to see this demonstration. I performed this experiment properly ONCE. Thereafter it always failed. I think it was because I used mossy zinc, or it could have been because I did not have exposed metallic zinc with which the copper could react. US pennies since 1973 are zinc with a wash of copper. I've wondered -- but have have not tested -- if mild heating would cause the zinc core to react with the copper to produce a layer of brass. If so, it would be beneath the copper on the surface, but should be tougher than the copper itself. Have you ever played with this?

[@Hassan_313]

Have you really turned into gold Or just the outer layer

[@akshay7291]

It is bad thing that you leave burner open

[@aubreyfarelli]

Or chem teacher did this experiment but said he would not tell us what happened to turn it a gold color. Thanks for explaining it.

[@nathanval759]

is it actually gold like in the periodic table or is it just colored gold.

[@butterflygroundhog]

Jonathan Valentin as they say in the video, it is a brass layer. brass is an alloy (a mix of two or more metal) and it has a golden color to it. however, unlike gold, which is really unreactive, other metals like copper and zinc (from the brass) will tarnish. this mean that the metal burns and change color to a not gold color.

[@HampusLohman]

lady, I love your accent.

[@huikhimtho8461]

Can I use copper strip?

[@akshayaakshaya9759]

how much time does it take

[@appug12]

How long does it take?

[@DragonRazor9283]

As far as how it went for me, it only took about 10 minutes. It takes several minutes to get the sodium zincate solution to boil and several more minutes to turn the pennies into silver. For the gold part, it takes less than 10 seconds to turn into gold, but keep the penny dry though.

[@Apollo6166]

would you maybe have a link to complete steps and materials needed for this experiment?

[@Cr4pSnip3r]

It's a much more attractive title "Turning Copper into Silver". I highly doubt anyone would actually believe that you can actually do this, so they probably just clicked to see what trick was being proformed.

[@kingaxron]

Now make it as heavy!

[@Pandadox]

THERE ARE ALCHEMISTS AMONG US

[@Budgetwheels77]

Madam you are the rosymary benson right

[@Rockysmith1296]

Your awesome at this

[@Spudwellington]

this video should be titled plating a copper coin with zinc and then brass....

[@shredsofhumanity]

i wonder how many people have tried to pass off copper as silver or gold this way for scams. As a kid i discoverd if i put U.S. pennies in my shoe, the sweat that bleed through my socks would cause it take on this really cool iridescence almost like an oil slick. I wonder if it is a similar reaction as this.

[@clementejrmilan199]

amazing ,what a chemist can do,is it a real gold? what "karat" is it?

[@drunkslav7280]

no it's not real gold

[@klintpollzzie2725]

No, she said it was just brass in the beginning.

[@ronnaldlove534]

its real. learn te periodic table. silver is right tabove gold. you heat it to exspress the zinc. banm ... gold

[@salchicha404]

what is the formula of sodium zincate/what is the molarity of the NaOH?

[@nuzhatashiq2023]

what is the formula of sodium zincate/what is the molarity of the NaOH?

[@zlatkovnik]

Where can I buy Zink?!

[@arabindabehera54]

Is silver real after reaction of cupper in chemical

[@WillLightfoot]

just call it how to plate copper with brass, that's pretty cool by itself.

[@ryuranzou]

Yeah this. Also how to turn into zinc.

[@mcarthur05]

Its that real gold??

[@HolyBookProductions]

bt how do you undo this effect.... since the stores will problably say that it is fake money.....

[@lorcancummins9301]

What concentration sodium hydroxide is it ??

[@royalsocietyofchemistry4447]

Hi, The demonstrator uses 100 ml of 6 M NaOH. At this concentration it is corrosive and should be handled very carefully, by experienced chemists.

[@amrendramishra545]

Send deatails

[@DragonRazor9283]

While I was doing this for my chemistry project, I accidentally breathed in some of the fumes whilst the sodium zincate was boiling. It tingled my nose a bit, but am I safe?

[@royalsocietyofchemistry4447]

Hi, glad you've enjoyed using the experiment for your project! See our health and safety advice for this experiment here: www.rsc.org/learn-chemistry/resource/res00000839/turning-copper-coins-into-silver-and-gold

[@TheBlueJamie]

ALCHEMY?!

[@sathyanarayanamolla4511]

Mom, are we make real gold. You said fake method

[@riyasoin6806]

can u tell me how u prepare sodium zincate??

[@DragonRazor9283]

Any information you need is in this website: www.rsc.org/learn-chemistry/resource/res00000839/turning-copper-coins-into-silver-and-gold?cmpid=CMP00005974

[@babbadudl]

I did this at school several times for the new kids to show them some chemistry-tricks :D Was always cool to see the effect. But the Zn-Solution smells pretty bad. When i watched the video I instantly had this smell in my nose :D (after 10 and more years)

[@mdsazidurrahman7741]

Is the coin turn into real gold?

[@supernerdy9354]

so fools gold? is it fools gold?

[@supernerdy9354]

thanks for the help i appreciate it

[@Binks129]

Royal Society of Chemistry Could you actually get gold through alpha or beta decay?

[@cub64]

She make their own pyrite....

[@michalismakouli579]

I have watched your video 3 times and i could not understand why you call a chemical Zn-plated silver and a Zn-thermal oxidation cold.Do you mean the colours?

[@mukulkumar6236]

Not so easy to make gold. itna easy hoto to koi gareeb nahi hota

[@minhluxuan3207]

some one can give me the reaction equation

[@jaydaksrules5316]

its called oxidation (facepalm)

[@DragonRazor9283]

Zn(s) + 2NaOH(aq) + 2H2O(l) → Na2 [Zn(OH)4](aq) + H2(g). This is the reaction between zinc and sodium hydroxide along with h2o to form sodium zincate. :)

[@honeybun2445]

itz not real gold..?! right..?

[@MrDanayr16]

what other pairs of materials/metals will have surface diffusion with a similar process?

[@manicmaster1]

Does anyone know where you can buy the materials mentioned?

[@bweetenicholas7159]

cool chemistry

[@super06141996]

Step one get allot of pennies.. Step two do this... Step three sell it to all the stupid people at my highschool, Profit!

[@12narutoshippuden11]

thay have the philosopher's stone

[@redmercury1159]

this is alchemy!! you didnt actually turn anything into gold or silver. you couldve cut all the complication out and just spray painted it! its basically the same thing.

[@Shoetiefly]

enjoyable and informative

[@madomaro203]

Can you show the percentages used in the experiment?

[@mathiasxx94]

Do this with a copper bar=profit :)

[@TRTeamGamerTR]

full metal alchemist sister :D :D

[@arkempire]

why are you shaking so hard? nervous cause im watching? :3

[@extendedp1]

Misleading title

[@Apollo6166]

Bubba why would you actually believe you could change copper into silver and gold? and even if you could you think there would be a KZbin video on it? everyone would have a surplus of it if that were true. they would be practically worthless

[@pablolopez3341]

Royal Society of Chemistry ck

[@fanyrs800]

"we appear to change copper to silver then gold" "WE APPEAR" dude she said it at the start

[@rajeshpawar239]

I'm 2 try but not work

[@DiamondDog900]

Technically, I think this would be called alchemy

[@nrako]

Wasting gas

[@nina99grateful29]

Funny, the China just pronounced their scientists can change copper into gold this morning. A day after Christmas 2018.

[@ortenciaavilaavila2991]

thats crazy

[@GothicSprinkalMuffin]

alchemy at its finest

[@ShekharKumar-js6oi]

Is it 24 Carret gold

[@xXMeecrobXx]

5 €ent are not made of copper they just are coated with copper

[@marrobles2726]

color really not real gold

[@supperstevenssss9580]

now I'm reach thanks lol

[@electroshock98]

i suddenly like alchemy

[@DarthGnomian]

Alchemy!

[@alchemyphilosophersstone2634]

Interesting

[@moralswithsaadyhamed6766]

You are excellent and I am so proud of you

[@ThatEspinosaGuy]

SCIENCE

[@luisff7030]

i will try this to protect the copper of the homemade PCB. i think will be cheaper than silver and stronger than tin.

[@VicariousReality7]

Quotemark gold quotemark God i hate when people describe products as silver

[@habibabbasi7206]

😐

[@abdullahawan6377]

Will u talk with me in email ???

[@Bloodyidit]

alchemy, my friend. also, SCIENCE!

[@manicmaster1]

Very interesting

[@JeePnoY1]

Only God can create Elements, quit messing with Gods money !

[@RuneDrake314]

NO, ALCHEMY!

[@NathanLarson01]

This is all too scientistic :/ lol

[@jmalone2071]

whatever it is filled with is what it is. As the same sense of in bread of humans..... just sayin... you aren't changing the metals. It's plated and not solid

[@Commanderwfls123]

no...Alchemy ;)

[@1zm0nster]

LOL

[@alberpajares4792]

JUST PROTONS AND NEUTRONS TOUCH, CHANGING THE NUCLEUS, NOT SO HARD .,.

[@alberpajares4792]

LIKE YOU CAN GET THE REST OF ELEMENTS BY HYDROGEN AND HELIUM, REALLY INTERESTING THEORY .,.

[@0olong]

I'm not sure what you're trying to say, but it sounds like you might not have fully understood this experiment?

[@546yourface]

ALCHEMY!

[@MOJODOJO67]

Gaius...
