Why does salt disove in water?

An essay question: HOW exactly does salt disolve in water? What properties of ionic and molecular compounds does it have? Charges? Weaknesses?

Why does Salt Dissolve in Water

This response submitted by Coyote on 10/28/2002. ( ) 68.42.185.174

Shannon;
Wow, I had to dig out my old chemistry book for this answer. Common salt, like we use on food, is a chemical called sodium cloride. Salt crystals are made up of molecules of sodium chloride. Each molecule has one atom of sodium chemically bonded to one atom of chlorine. The atoms take the form of ions, which have an electric charge. Sodium ions have a positive charge and chloride atoms have a negative charge. When salt dissolves in water, the ions separate and become surrounded by molecules of water. Hope that helps you out.

It doesn't

salt does not dissolve in water completely. If you evaporate saltwater you will have a pile of salt left. That's how they extract salt from the ocean. In simple terms that is anyways. So how is that for an answer? Go do some more research now. Sugar will completely disolve, salt will not.


Dissolved Sugar...

...will also crystalize. Dont believe it?...try it.

El coyote is correcto. Salt is an ionic compound and therefore ionizes in a solution with a molecular compound like water. Unless you attempt to make a super saturated solution of salt in water, all of the salt WILL ionize. The evaporation of water from a salt water solution will indeed leave the salt, but the conclusion that all of the salt did not dissolve is an assumption inconsistent with the observation. But then evidence strongly suggests that pigs are smarter than coyotes, so the apparent discrepancy in the reported information may well be due to the nature of the contributors to the conversation. That's all I have to say about that!


Applause, applause!

Coyote I didn't realize you were such an intellectual type! Excellent
guys! Now, how about some one going to the recent posts on More Salting
Questions and get things straightened out on the hygroscopic propertied of
salt, maybe even throw in a little on the effects of salt on hydrophilic
proteins and naturally occuring systemic organic acids and unsaturated
lipids?

Pigs are recognized as being in the top ten of the intelligence scale in
the animal world. I raised a Duroc once in the same manner as one would
a pup. House broke to newspaper, basic obedience training with out the
use of lead or harness, and very clean by nature. When it got to the point
that a whole Sunday newspaper wouldn't contain the yellow river, and she
was lifting the dining room table when she walked under it, she was given
her own little pig palace out side. A number of months later one of the
area hog farmers wanted her for a brood sow, so he got another brood sow.

I had a coyote pup once that insisted on eating humans alive. A fellow
came along and wanted the coyote real bad, and was I glad.

The fellow had the coyote for years and years, it died of old age. The
pig was no doubt turned into whole hog sausage after doing her short tour
of duty.

So which would you rather be, a sweet pig or an ornery coyote? I'll
deliberately avoid the intelligence issue of the two.


'scuse me,

that's Yet Another Salting Question.


Ha ha ha

now I don't know whether I suppose to feel insulted or honored? BS in Chemistry I flunked it once in school. Must have been when we covered the subject on ionization. Oh well. I was halfway right, right? LOL. And Glen, watch out. There are two Coyotes on this forum and even I with my superior intellect haven't figured out which one answered the salt question correctly. Ah another challenge for you. I know you can handle it. LMAO.

Superpiggy;
How dare you not know which Coyote wrote that. I will send out the scorpions now. Watch your mail.....LOL

SP,
Keep your chins up! Your intelligence is exceeded only by your good looks.


What about Boiling point elevation and freezing point ...

This response submitted by Mike Dunbar on 10/29/2002. ( ) 207.230.218.162

depression? Here's a good one, why is does water become less dense as a solid,(ice)? Good thing, otherwise lakes would freeze solid.

Why is salt added to icy roads or to boiling water when cooking at high elevations? What does high elevation have to do with it?


By the way skull boilers...

This response submitted by Mike Dunbar on 10/29/2002. ( ) 207.230.218.162

When you add sal soda or baking soda, what does that do to your boiling water temperature? Ions, ions, ions. Superpig, its tough to get a skull cleaned in water up Nort here hey, too damn cold.


Great Mike

you just couldn't leave good enough alone. Now I am sitting here beating my brain with all your new questions. Still trying to digest Glen's answer. There goes another sleepless night and all in the name of science. Ahgh.


You are wrong!

You are wrong about the sugar all dissolving because if you get a microscope, there will be some left over, just a small though!
