Hello. I realized that by putting simple nails in sulfuric acid (a pH down for aquariums, ~0.55 mol/L), I'd wind up with iron sulfate. According to Dr Raymond B. Wailes, I was supposed to get a green-ish, fizzy solution (from dihydrogen H2 and possibly acetylene C2H2). I did get the fizzy solution, but never the green-ish color: as soon as I dipped the nails, the solution went purple-rose. After a day or so, the solution is back to transparent; dissolution of nails is still ongoing (still seeing lots of tiny bubbles). What can possibly be in solution, according to color I got? Are vanadium, chromium, zinc or other elements present in the nails reacting with sulfates instead of the iron? Did search for a purple-ish sulfate-compound (eg sulfate chromium), no success. Should I have used old rusty nails instead? Hopefully, you can help! Thank you for your time, have a good day.
