You break these subjects down so well, and now I love that you slow it down because thats exactly what I need. You really make things a lot easier to understand.

Muslim Trump supporter M.AG.A I’ve never been on Tinder and I don’t do Instagram either. My esteem isn’t measured by likes, it’s measured by successes and I’m happy to say that I’m graduating with a bachelors of science in biology with minor in psychology this year so I guess you were wrong... Don’t worry, I don’t expect you to have grown from your incorrect assumption from a year ago, nor do I expect an apology, as that would show too much emotional intelligence and this time, it looks like you’re the one without it. Have a great day!

[@tdewitt451]

you're right, they're very strong. but Na+ would rather be surrounded by water than by Cl-, so it is willing to float away from the Cl- if that means that it will be able to have a lot of contact with water. i'll do a video on this shortly. the process is known as "dissociation" and "solvation." there might be some good videos others have made on this. great questions!

[@mpag6195]

I am confused on the process that NaCl breaks up into its atoms in water. would this not mean that the Cl would be released as a gas and the Na be left in the water to react?

[@carmelo_gonzalez]

@@mpag6195 What you are talking about is a physical change occurring. There is no physical change occurring when an ionic compound dissolves in a solution by a solvent. What ends up happening is that intermolecular forces occur between the individual ionic atoms and the atoms of the solvent (in this case the solvent is water).

I like the way you physically demonstrate how something works using your hands' gestures and body language which I think are the core forms of communication. Also, your tone of voice, not loud, not low, and not coarse or faster. It is just the right combination of how a genius like yourself gives meaning to a difficult subject to an uncommitted or disinterested audience until some of them develop interest and yearn to learn about the subject. Thank you!!

Holy cow, first time seeing a video of yours. I'm in love. Instantly subscribed in the hopes that your other videos are this well made, well thought out and expertly delivered in such an easy to understand way.

[@georgelefrancois8256]

Your videos are excellent. You speak clearly and my kids and I like your clever presentations with the pre-made visuals. After watching your explanation of the ionic compound salt dissolving I wondered why the water tastes salty and not like chlorine and sodium.

[@tdewitt451]

What we think of as "salty" is the taste of Na+ ions. It is impossible to taste salt without dissolving the NaCl. Think about this: dry your tongue completely and then pour salt on it. You can't taste anything with a totally dry tongue. You need to be able to dissolve the salt in order to taste it. And what you taste isn't undissolved salt, but mostly Na+ ions.

Thanks Tyler.

Hi Tyler, firstly thank you for a brilliant set of videos which I am thoroughly enjoying watching! Your teaching style is in my opinion second to none and very easy to follow.

The short answer you gave was good for me, but I look forward to hearing more about it later! Thanks once again!

[@GrandmasterofWin]

You are a GOD of teaching. Chemistry is a complex subject, so the majority of the time the Professor/teacher takes for granted their knowledge base, and just how complex a puzzle it really is. Simple statements like your title can be hugely helpful in linking real world experience to the realm of chemistry. Thank you, sir.

[@firsh]

You are an excellent teacher, wish there was people like you in schools. I have a question. If an ionic compund dissolves that way, why doesn't it change the taste or other characteristic of salt? Why does it still taste salty? Sugar I can understand because sugar molecules remain there, but spread out. But the salt one looks broken apart.

[@chrisgemmell102]

[@siefele]

Forgive my ignorance, but if salt breaks apart into the individual atoms -- and sodium is explosive in water, and chlorine is poisonous, how can the water still be "salty" -- and not be a compilation of explosive poison?

[@Naijiri.]

***** Then which one are we tasting as salty if they are no longer together...

[@filipbahunek2504]

Poke Playah Both of them. That is what tastes salty to us even when we eat solid salt, since when it comes into contact with your saliva(Mostly H2O) it dissociates into Na+ and Cl-.

[@MartClips]

i wonder that too, did you get your answer?

[@zer0kelvin212]

Hello, my hypothesis would be that pure Na and pure Cl are highly reactive and highly unstable individually. Na will mostly bond with a halogen and Cl will bond with other(s) atom(s). If you take Sodium alone, it can be easily oxidized because it has a lonely electron to lose, being in the Group 1. The Na wants to get rid of this extra electron. Therefore, the electron contains a lot of potential energy to lose, which makes its reaction with water explosive. As for Cl, it is the second best oxydant, which means that it is the second strongest stealer of electrons. But NaCl combined together is a different molecule therefore it has different chemical property. Cl really attracts the electron and Na really wants to get rid of its electron, so they combine well together and become more stable and less reactive so their reaction in water doesn't realease enough energy to create so much heat or explosion. please correct me if my hypothesis is wrong.

[@carlosrios5363]

its because when any ionic compound dissovles in water, their ionic bond is not broken, even though water seperates the atoms in the solution. that is why salt in water is still salty as the connections between nacl is still present, which means they still will have same physical properties.

[@Fireflymeadow]

Thanks for the awesome video! I didn't, however, get WHY sugar breaks up into molecules, as opposed to salt which breaks up into sole atoms.

[@eoryvera]

I'm glad to have such explanatory videos available for anyone with internet connection. However, there is a serious error in the explanation: the "sugar" molecule presented is not a sugar, but glycolaldehyde. Glycolaldehyde is related to sugars, and has the same proportions of carbon, oxygen and hydrogen as most sugars, but it is not a sugar. It would be good to see the video updated; the sugar being a real sugar, e.g. glucose.

why do some covalent substance dissociates when dissolved in water? Exp: 1)Hydrogen chloride (covalent compound) will dissociates into hydroxonium ion and chloride ion when it reacts with water 2)Ammonia (covalent compound) will dissociates into ammonium ion and hydroxide ion when it reacts with water

[@frankiethefrank]

This was a great video! Sir, I have two questions: Firstly, you've explained very well about what happens to the molecules when they are in the water, and hence why I can taste the sugar in the water (because, hey - it's still sugar!). But since the NaCl has broken down into separate Sodium and Chlorine according to the explanation, how come it still tastes like salt? Or is the taste of salt simply the taste you get if you shove a lot of chlorine and sodium into your mouth at the same time? Secondly, since the molecules of sugar are clearly a lot bigger than the the individual atoms of sodium and chlorine floating around in the water, how come you can dissolve so much MORE sugar in water than you can salt? Many thanks!

[@TheTopnotchEngr]

I think this answers question 1: www.quora.com/If-common-salt-dissociates-into-its-ions-when-dissolved-why-does-the-water-still-taste-salty/answer/Pavitra-Ramdas?share=0c15dba7&srid=udhcy

[@GameRanger46]

look, sugar is dissolved as a molecule that is compact which occupies smaller area as compared to na and cl that spread apart. Consider an atom, you have almost complete mass in only 1% area while elctrons with almost no mass cover 99% area and have even saturated the area it covers (meaning more electrons cannot fit into that place)

[@angelaspivey4494]

[@LiborTinka]

Some alkaloids form salts, e.g. harmine hydrochloride, which readily dissolve. However, if we add base to the water (e.g. NaOH), it forms NaCl and H20 leaving the alkaloid with positive charge and the alkaloid becomes insoluble. Why is that? Why water prefers Na and Cl ions to stay dissolved freely regardless of charge, while the alkaloid crashes out from solution? It seems the overall charge in the water tends to be neutral and some molecules that puts it out of balance are not allowed to stay dissolved.

[@katerawsaerialist844]

Finally found the real bloody answer to this question. It depends if its ionic or covalent.

[@franciscomendez8863]
