Thanks for the word of caution. Just to be safe, I just mixed a massive amount of both household strength vinegar and baking soda and noticed no temperature change. I get stuck neutralizing massive amounts of acid periodically at work and it'll usually bring what I'm working with to a boil, but then again I'm dumping anhydrous NaOH to several liters of >30% nitric acid.

Phenolphthalein is a good idea. I'll have to "borrow" some of that from work. The bottle that we have is so old that it doesn't even have a bar code on it!
