I also keep NaOH and phenolphthalein, and currently I've been keeping some K2MnO4 solution because I've been researching it
lately, although it's not something that I'd have normally. Normally I have NaHCO3 solution in a wash bottle for neutralizing acid spills,
but I used it all up recently. I need to mix up some more.
And of course, the usual suspects that you mentioned, except not HNO3, because I don't have any. I really need to get some one of these
days. |
