Dissociation of salt

[steveu235]

Best eplanation I have ever seen, well done thanks

[SuperNerdGaming]

The bucket of salt looks like a c**k

ياريت نعرف نستفيد من الفديوهات االتعليمية الجميلة دى

[HotRock2010]

is there any animation videos like this that show how acid dissolves metals or can someone explain it to me? thanks

[fuzzybudgie]

@HotRock2010 Metals undergo a single displacement reaction with acids, e.g. Metal + HCl --> metal chloride + hydrogen gas (H2). It appears to "dissolve" the metal because the ionic metal salt produced (e.g. metal chloride) is usually soluble. It dissolves in water as shown in this video (remember the acid is aqueous).

[HotRock2010]

@fuzzybudgie ok thanks, now I understand. :)

[paulofighters]

You can taste it because the ions and anions are like "expectators" in the solution, they'll never disappear, they are still there.

The proof is that if you boil that solution, the H2O will evaporate the salt will be left behind. Remember that anything can be destroyed as states the Law of Mass Conservation.

[masteranimation2008]

I thought Sodium and Chloride were poisonous on their own. If water separates a Sodium Chloride(salt) molecule, it should kill us right?

[kpluch11]

@masteranimation2008

Pure sodium metal (Na) and pure chlorine gas (Cl2) are definitely poisonous and you wouldn't want to consume them. These are sodium and chloride ions, which are totally harmless in moderation.  Check a bottle of Gatorade...it contains electrolytes like K+ and Na+. Your body needs them.

[UMChem125]

Would it be ok if I embedded this video in a project I'm working on? The explanation and the animation of what is going on is one of the best ones I've come across

[djancak]

shouldn't the water be pulling out the whole sodium chloride molecule rather than the separate sodium and chloride elements?

[Peopleunit]

Is there any sort of thermal change associated with this, or its counterpart, recrystalization?

[randomdudeoncrack]

how come there has to be 5 H2O on every Cu+ and SO4+?

[Swizz884]

@randomdudeoncrack balance : (  

[chemy999]

@randomdudeoncrack there doesn't, that's just one form of copper(II) sulfate. if you heat it then at a certain temperature two of the water molecule will go away, then if you heat it more another two will go away, then if you heat it still more then the last water molecule will leave, if you store it in a dry environment then the anhydrous form will stay that way and instead of seeing a purdy blue crystal or powder when you open the container you will see a darkish brown-white powder

@joesipp yess yes u cn download.

[joesipp]

Can I download this video for a demo I am doing?

[Zartushta]

NaCl-------(Water)------------­> Na + Cl

So it's decomposition reaction isn't it?

Why the hell is this called dissociation?

[RedJoe187]

@Zartushta because it ionizes in an aqueous solution.

[Evi1M4chine]

But if it is dissociated, why does it still taste salty?

[felipe200794]

@Evi1M4chine because it's not completely dissociated...the material constant of water is 80

[chemy999]

@Evi1M4chine because the taste is caused by the ions. if both your tongue and salt were dry then salt that you ate would not taste salty

[Archtus]

@Evi1M4chine cause your mouth also contains water and salt dissolves in your mouth thats why

[DoS37]

@Evi1M4chine

Because you feel the Cl- ions. You have never tasted NaCl, so how do you know it tastes salty? You've only tasted Cl- ions.

[krusko6]

Isnt H2O also suposed to be dissociated on H3O+ and OH-

[Bloodemi90]

@krusko6 for sure. i think too that this is wrong :D

[CORTASH55]

@krusko6 well almost , its actully H+ and OH-, but this is an equilibrium reaction meaning it constantly goes from H20 to h+ and OH- and back again so u still get h20 as a whole molecule.

[maciejwrotek]

why does not sodium react with water forming NaOH and heat ?

[maciejwrotek]

@thechemprofessor why ? U say metalic sodium has one more electron ?

[thechemprofessor]

That is corect. Sodium has 11 protons and 11 electrons. Salt contains Na+ ions, which have 11 protons but only 10 electrons. The atoms have already lost one electron, and are no longer reactive. In essesnce, the sodium has already reacted with chlorine ro form NaCl.

[spotlightman1234]

@maciejwrotek sodium ions are already reacted so they dont dont react

[hbjon]

Are the sizes of the atoms correct relative to each other?

[NoSz4]

very cool.

[kasphytlove]

omg tnks alot

[kasphytlove]

that is so cool!:)

i was needing that for a project thanks for the info.

[JohnnyTheChemist]

Not exactly...

Cl^- * 4H2O forms tetraedric complex

[Qui014]

Dissociatie van zout: hoera!

Het filmpje waar iedereen op wachtte

[simpsonstewie]

due to polarity of water molecules it is a great solvent

[theyoungster2]

cool! i always wondered how that worked
