Hi, I'm trying to figure out how to dissolve metallic Au in solution, for an electroplating solution, without the use of Nitric Acid, Cyanides, or other chemicals which i cannot obtain. I can obtain many more common (less suspicious and dangerous) chemicals, such as concentrated HCl, H2SO4 and H2O2, NaOH, Urea, and many other things. I thought about distilling conc. H2SO4 out of KNO3 but i don't have a proper distillation apparatus that will handle this. I read somewhere that a Urea solution will complex with gold, forming a solution - is this right? does anyone know the details needed to make this work? Could trichloroisocyanauric acid, or Na dichloroisocyanaurate, having a structure derived from cyanide, be used to form a suitable solution?
