Please Help!
For gold dissolution in Sodium Thiosulfate solution, I have to add FeEDTA at a concentration of 0.002 mole for one liter solution. I have with me Ferric sulfate and EDTA (Ethylenediaminetetraacetic acid) separately. Please advise me how many grams of ferric sulfate and EDTA I have to dissolve into the solution respectively.
Thanks!

People use copper as a catalyst. Oxygen is necessary for oxidation. The process is very touchy.
