	Some issues: * You have two chlorates * you should take the sulphur based versions (sulphate, sulphuric) * you should take "bicarbonate" for "hydrogen carbonate", "bisulfate" for "hydrogen sulfate" etc * you should take "ethanoic acid" for "acetic acid", "ethanoate" for "acetate" * There's too much time; I got all 34 with 4:52 remaining and I got many by guessing * Also, ammonium isn't an acid or an anion -- it's a cation! :P Overall, I like the quiz, but it's a bit rough round the edges.

	Technically the ammonium ion is an acid because it can donate a proton to water to form ammonia (it's conjugate base).

	I agree with rhebus that you need to add ethanoic acid for acetic acid, bisulfate/bicarbonate for the hydrogen anions, and the alternate sulphur spellings. I'm not sure I agree about the time... there isn't much you can do to cut out time for guessing in a quiz like this. There's only a few possibilities if you're at all familiar with chemistry naming rules so when you design a drill activity like this you just have to deal with the fact that guessing is a plausible strategy for someone seeking a high score.

	also, perchlorate (ClO4-) needs a negative charge

	Thanks for the feedback. I didn't expect others would find or play this quiz. I made it to review for my upcoming chemistry exam, so I didn't worry too much over format or time.
