In order to neutralize, there must be the same number of moles of hydroxide ions as hydrogen ions. I've been searching around the web and the consensus seems to be sodium salicylate dissolves poorly in HCl because it would form salicylic acid. - khaverim Feb 1, 2016 at 4:05 Filling the burette, measuring out the alkali into the flask, and titrating it until it is neutralised takes about 20 minutes, with false starts being likely for many groups.
