it happens because it is a supersaturated solution, and your finger becomes the seed

i`ve found myself somewhat gripped by understanding this process fully, anyone else who`d like that lil bit more detail i found some good info:
http://home.howstuffworks.com/question29...
i`ve not found anywhere the explaination as to how the chain reaction continues after it begins. it seems the crystalised sodium acetate solution particles act as nucleation points for further crystalisation. appologies if everyone else worked it out ages ago and i`m rambling on. Crowe

A saturated sodium acetate solution freezes at around 60 degrees (140F). So basically unless you put the stuff in the oven, liquid sodium acetate is ALWAYS "supercooled" (i.e., below it`s freezing point while remaining liquid). It doesn`t have anything to do with refrigeration or "exposing it to heat." A liquid sodium acetate solution at room temperature is supercooled.

Moving the solution gently or exposing it to air does not trigger the reaction because it does not introduce a nucleation point (a foreign particle large enough to attract/form ice crystals). This is how the demonstrator is able to pour the solution into the tray without triggering the reaction. If he poured much faster or if there were a large dust particle in the tray, the reaction would have occurred immediately on contact.

i like science, yeah, nowt wrong wid bein a nerd. what`s the freezing point for the sodium acetate solution? 54 celius? i made the assumtion that introducing heat into the solution (when at 4 ish celcius from the fridge) triggered a -chemical- exothermic reaction expelling heat from the solution bringing it down below its freezing point. seemed the logcial answer as the heat given out by any part of the solution reacting would in turn trigger the reaction throughout the rest of the chilled solution (well, supercooled, as it seems). if agitation of the solution or introducing a foreign substance would trigger the reaction, i would have expected moving the solution or exposing it to air to have such an effect. though, by the same logic, i did wonder why exposing the solution to heat to when removing it from the fridge didn`t trigger the reaction. we didn`t use the term supercooled when i was in school/college, so don`t take the pi**, freeman, i ain`t thick. i asked where not what.

@Crowe: " where did the whole `supercooled` thing come from? they didn`t use anything that cool (pun intended)"

Do you know what the term "supercooled" means? Do you understand that not all liquids freeze at temperatures you would consider "cold"? The reason this sodium acetate solution freezes so rapidly is because it`s ALREADY below it`s freezing point and simply needs to be agitated or have some foreign particle introduced to begin the chain reaction of ice crystal formation. That is what the term "supercooled" means. By definition. Why do you think it freezes when he touches it? Because his finger is really cold? No, because the freezing point of the solution has already been reached. We`re not talking about rocket science here, people. All you have to do is Google "supercooled" to understand. You know how to Google, right?

that`s awesome :) looks real fun. i dunno but people seem to have got confused over the whole exo/endo - thermic reactions part. exo - releases heat, endo - absorbs heat. for the solution to freeze it would have to get colder (ie. release heat) and therefore go through an exothermic reaction. where did the whole `supercooled` thing come from? they didn`t use anything that cool (pun intended) ;) Crowe

Umm, what are you two talking about? It IS supercooled. I mean, I hate to be negative, but try to understand what a word means before posting snarky comments about it, okay?

@krusty2514: "They were wrong in the video. In exothermic reactions, heat LEAVES hence the exo part of exothermic."

Uhh, yes. Heat LEAVES the reaction, hence entering the surroundings. Thus, "it gets hot" (as in you will feel heat if you touch it or the container in which it is taking place).

So how was the video wrong, exactly?

Phoneix you cant improvise by figuring out the proportion like you said you did. First you must have an 8%. Percent concentration does not have anything to do with proprtionality because for teh reaction to occur it should proably be 8 percent.If you are making your own acetate then you know that for the reaction to proceed forward and be exothermic, its got to be 8 percent

They were wrong in the video. In exothermic reactions, heat LEAVES hence the exo part of exothermic.

TO get to 8 percent here is an easy way if you have some kind of knolwedge of chemistry

here is the math formula for it for easy computation

(molarity1)(Volume1)=(molarity2)(volume2)

so for M1 you would put 5 percent Volume 1 you put whatever volume you think is good for you. Molarity 2 you put 8 percent Volume 2 you put an X because you are solving for it.

Use math to find out how much volume must evoporate to get an 8 percent solution. Ask if you need help.

It IS supercooled. The melting point of sodium acetate is 58 °C. Since room temperature is roughly 23 °C, it should be a solid, but it remains in its liquid form.

I made sodium acetate using vinegar and baking soda. I only had 5% concentrated vinger so I figured out the proportion so it would be like 8%. The baking soda was old cause it was use in the fridge. Anway I got the acetate made but it was a little on the brown side. I brought some water to about boiling temp (190 F) and added quite a bit of acetate. I put it in a pyrex mesauring cup and put it in the fridge for a good 40 minutes. The acetate just settled on the bottom and some was suspended in the water but it didn`t do anything. Can someone tell me how to do it right and if the impurties in the baking soda would have caused in to wrong?

Sodium Chloride, NaCl, is salt.

Sodium Acetate NaC2H3O2 is a component of the fizz made when you mix baking soda and vinegar together.

He creates a supersaturated solution, which means that a single particle can start the acetate percipitation. Unfortunately, that isn`t ice =P

that`s cool. it`s just like some renewable hand warmers I have. After you`ve done the experiment, you should be able to put it back into hot water and repeat the whole process. I don`t know if somebody already said this, but I believe that happens b/c by letting the mixture cool off, you make it unstable(which is why one little touch will start that whole chain reaction). There is more dissolvent in the mixture than it can hold at a cool temp.

According to Wikipedia, you can make your own sodium acetate using baking soda and vinegar.

84 grams of sodium bicarbonate react with 750 g of 8% vinegar to make 82 g sodium acetate in water. By subsequently boiling off most of the water, one can refine either a concentrated solution of sodium acetate or actual crystals.

Thanks for the props, notapervert. I was a chem teacher for 5 years. You really can`t use sugar, the solubility (how much dissolves) is too low. When water is heated, the solubility of sodium acetate skyrockets. When cooled, the solution becomes "supersaturated". Kungfu sage is correct. That starting crystal is called the "nucleation site". Look up nucleation.

the reason it didn`t solidify when it was poured into the pan is because for it to "freeze" it has to have something to freeze onto. the glass pan was clean and smooth so there was nothing for the crystals to form around. but when you touch it the crystals form on your finger and then the crystals form on other crystals and so on till it is all solid. It`s the same thing with the bubbles in a pop bottle when you drop in the life saver mints.
