Good quiz, but you should accept common names for the acids. For example, for HC2H3O2, the other names are acetic acid and vinegar.

Good quiz but could use some cleaning up/explanation with the right half of the answer list. I wasn't sure what you were looking for at first and there doesn't seem to be much rhyme or reason for the acids and bases listed. Also, for Hg2(2+) should really be mercurous and not mercury. Acetic acid really should be acceptable for the last one. Myself, I wouldn't accept vinegar as being interchangable with acetic acid since it only comprises about 10% of the makeup of vinegar.

For the last one, ethanoic acid, acetic acid, and CH3COOH should all be acceptable. Also, there doesn't seem to be much logic in the selection of compounds in the right column. Why Sr(OH)2 but not, say RbOH or LiOH?

Listing weak acids is a bad idea. Why? Every acid that isn't one of the six strong acids that you have on here is a weak acid. There's no reason I should guess phosphoric acid and not arsenic acid, or acetic acid and not oxalic acid. There are too many possibilities.

Agree with above criticisms, also, dichromate should be Cr207 2-
