uh how do you make it cause i have a science fair in like 3 weeks so ya

I have an Instructables page... Go to dub-dub-dub-dot-instructables-­dot-com, search for "crystallization homemade sodium acetate". :-)

not true. many chemical reactions are easily reversed. Rechargeable batteries, for example. The burning of hydrogen gas to produce water can be reversed pretty easy too. There are plenty others but I think you get the picture...

you dont need to be in the 90s to know how to seperate NA from Cl

Lolz

ha ha ha cows

[ripper99100]

How will you get it out ? :P

wil reheating it work ?

[hceriseh]

is it sth like the warm packet?

[dragonridley]

Why is it colored?

[gehtomacgyver]

well so kinda what i said but not exact so thanks

[indigoandblack00]

Actually, the answer is "yes and no", but not the first time. Once it crystallizes completely the first time, you could even pour off any excess fluid - at that point, you're left with exactly enough water. However several cycles of reheating could then evaporate off enough water so that you can never fully redissolve the crystals.  It's at that point you'd want to add water, a small amount at a time.

@ObamaBiden20082012 dosent anyone know that sodium"salt" makes water melt thats why fresh water even cant flash freez lol because of the m-cules in it wont allow the bonding : )

[jeffmckishen]

if this is the case then throwing salt and vinegar chips into a lake would freeze it

[alchemist1791]

@ObamaBiden20082012 Actually, the soultion already has the Sodium Acetate added, and in order for something like freezing of a lake to happen, it would also have to have the equivalent amount of sodium acetate in it.

[ObamaBiden20082012]

whatever you do don't throw that in a fresh water lake!! It will freeze all the normal water, any water that gets in contact with turns to room temperature ice like in the video. Its a chain reaction I think, just a small bit could turn the great lakes to permanently frozen. This isn't a problem with the ocean, because the salt prevents this so called "hot ice" from occurring!! Obama 2012!!
