blackhole123 Posted August 28, 2007 Posted August 28, 2007 http://www.noob.us/miscellaneous/how-to-make-hot-ice/ looks like fun, i need to try this.
Fuzzwood Posted August 28, 2007 Posted August 28, 2007 Its simple actually: neutralize acetic acid with sodium hydroxide and evaporate the water.
YT2095 Posted August 28, 2007 Posted August 28, 2007 sodium carbonate is better (or Bicarb). unless you have Indicator paper handy? with these 2 you will see that the reaction is finished when you add a little more and no bubbles form although I would add or keep the excess towards the Vinegar side, as that is easily driven off with gentle heating.
John Cuthber Posted August 28, 2007 Posted August 28, 2007 A couple more things to think about. Sodium acetate is very soluble in water. It only takes 60 ml of boiling water to dissove 100 g of the salt. Vinegar is only a few percent acetic acid typically 4 or 5%; the rest is mainly water. You are going to need a lot of vinegar and a lot of patience boiling off water to do this experiment on the scale in that video.
YT2095 Posted August 28, 2007 Posted August 28, 2007 LOL, Yeah and it makes the place stink like a chippy for days too! I used GAA for mine, but I still had to thin it out a little with white distilled vinegar to get the reaction running smoothly. in addition, it`s also important to select your Vinegar correctly too!, you can get 8% pickling vinegar that will work fine, but some has sugars added and other junk. a good way to test is to boil a small amount off and have a look to see if during this it starts to go Brown, if it does then you may have problems so don`t use it.
John Cuthber Posted August 28, 2007 Posted August 28, 2007 You can always distill the stuff to leave the caramel and sugars behind but I'd look on ebay for sodium acetate. http://cgi.ebay.com/Sodium-Acetate-Anhydrous-FCC-Food-Grade-Powder-1LB_W0QQitemZ130146100710QQihZ003QQcategoryZ104233QQssPageNameZWDVWQQrdZ1QQcmdZViewItem (I am not afilliated with the vendor, not can I offer any evidence of their quality- when it coemes down to it I can type "acetate" into an ebay search)
