Hello! Today I have for you a wonderful experiment "hot ice". This experiment can be repeated by anyone!
We need the vinegar (70%) and baking soda.

Mix 1 kilogram of vinegar, 978 grams of baking soda and 200 grams of water. We can observe how carbon dioxide is released!

A few hours later, we got the sodium acetate trihydrate.

We need melt the sodium acetate trihydrate in a pan.

We have obtained a clear liquid.

Put the solution in a bucket of cold water and cover with a lid.

Even a small crystal of sodium acetate is able to start the crystallization process in the cooled solution.

<p>Чего такая кастрюля страшная? ))</p>
<p>Im confused. What exactly does this do?</p>
<p>I did this few years ago. </p><p>https://youtu.be/PhXQY8NQOsc?t=1m37s</p>
<p>THis is so COOL!</p>
<p>Where could you get 70% vinegar? In my country 40% is the strongest you can get in shops, and vinegars above 30% are really rare.</p>
<p>He didn't mean 70% concentration. He just didn't explain it well. It's just regular 5% vinegar.</p>
<p>That's a very impressive video. This stuff gets quite hot. Doesn't it burn your hand?</p>
What video I see no video and I don't see any instructions just a off I can't load cos I'm not on a device that can't open them
there is nothing telling me how to do this.
<p>Nothing? ...You mean besides the step by step instructions in the video, and the ones in the description? </p>
<p>You can click the Play button on the video to watch the step by step I believe...</p>
<p>Hot ice is fun to play with. For a more in depth explanation of the &quot;how to make it&quot; process, check out the instructable posted by C Stokenbury in December of 2011.</p>
<p>What is the link to that instructable please?</p>
<p>This is the link @maint1 was referring to...<br></p><p>https://www.instructables.com/id/How-To-Make-Hot-Ice-Using-Homemade-Sodium-Acetate/</p>
<p>By the way vinegar is actually good for a person to consume. My mother used to make vinegar pies for my dad. I refused to eat them. Recipes are easily found on the internet. I don't know how much acetic acid the body could handle, but that wouldn't be a good thing to experiment with. </p>
<p>Many people do eat pickles....</p>
<p>I've made it a few times but it is hard to get it before it turns solid. Just combined white vinegar and baking soda as part of different experiment. (floating bubbles on CO2). Used up the baking soda until no bubbles, poured of the liquid (filtered it) and then slowly evaporated the sodium acetate to just the right concentration.</p>
<p>Love chemistry!</p>
<p>Thank you for posting this! Maybe I'll try it when i get the time!</p>
I haven't made it yet, but I will! This is fascinating! Thank so much for the video. It answers all my questions, perfectly!
<p>I use to have a few hand warmers for hunting. And there was a little metal disk inside the liquid sealed plastic pouches. And if you clicked the metal disk, they would crystallize like this and get very hot. And that heat would last for a few hours keeping your hands warm while hunting. Then you put them into either the microwave or a pan of boiling water and they would go back to liquid again so you could use them over and over. But after some cycling times they didn't work as good and had to be replaced. This is the exact same process. Any disturbance will set it off to crystallize and heat up. </p>
<p>Amazing! Thanks for sharing!</p>
