Homeade Sodium Acetate
I'm wondering, does anyone have any tips/general procudure for making homemade Sodium Acetate (from baking soda + vinegar)
Like how could i purify it to higher concentrations; should i boil the vinegar first so the Acetic Acid conc. is higher, or should i mix the stash
first, then boil off the water then??
And any tips on removing the impurities??

Easiest way to remove impurities without using a ton of activated carbon is to filter by gravity, and then slowly recrystalize. Remove the liquid left
over, and redissolve the crystals

You'll find that sodium acetate is not very soluble in the standard 70% isopropyl alcohol, while much of the colouring substances are. Wash the crop
of crystals in the alcohol, which can be recovered for reuse by simple distillation, and then recrystalise.
For this application coffee filters will work, although some of the sodium acetate will pass through the paper - it's designed for coffee grounds
which are pretty big. If you make a hot solution, you'll need to keep the filter hot too else it will quickly clog. A dilute solution will give no
problems, then slowly evaporate it at 20 to 40 C.

Actually this is one of the experiments I did with my kids - without caring much for purity of the product. Making an oversaturated solution - or "Hot
Ice" as it is called in that video -, worked perfectly without any purification at all. We used simply white vinegar and baking soda. It just turned
brown after heating; but apart from that it worked perfectly, and my kids were excited about their "heat bag". So if you just want to make that, if
you get really clear white vinegar, it is very easy.
For other purposes you might need purer sodium acetate of course, it depends on what you want to do with it.
