I have not used ammonium perchlorate. I have used ferric chloride, cupric chloride, HCl +H2O2, and H2SO4 + H2O2.well, ok then (muhahah you should have not asked for specificness )
Right
1) Which one when spilt onto skin will cause the least damage
2) Which one is the safest to store
3) Which one is least likely to affect a person in long term
4) Which one would you rather have a kid handle ?
5) Overall, which one is the most safe to use?
Ammonium perchlorate would not be an appropriate chemical for etching copper; you must be thinking of ammonium persulfate.1. Probably the ammonium perchlorate.
2. No idea.
3. Limit exposure - not really an issue. Pour, etch, pour back in container.
4. None of them. Under any circumstances (thinking 4 year old grandson).
5. I would choose FeCl. You can see it easily, and so clean it up. Despite the horrible stains, it doesn't fume.
