How do I ionize (oxidize) Platinum metal. What to do to desposit Platinum on Copper metal ?

Hello Guys! I'm willing to use either polar protic (H2O) or polar aprotic solvent (CH3(CO)CH3) or (CH3OCH2CH3)for the Platinum salt if I become able to create it. Does these work for PtCLx or PtNO3x, PtSO4x ? I wonder if you know another salts for these solvents if they are able to disslove of course, please help :)

i think you could use chloroplatinic acid (platinum dissolved in acquaregia), and a platinum anode.
i don't know if you could use an aprotic solvent, or at least i never seen it used for plating.

I don't have Platinum in a shape possible of being used as anode. The Platinum piece I got is attached somehow to Bronze. Even if I cut the piece somehow and separate it mehanicaly, then melt and reshape it, I won't have then Platinum to dissolve in your proposed aqua regia as my quantity is very small. Is it possible to use Carbon anode, ChloroPlatinic Acid, and Copper cathode ? Won't the Carbon fool the Platinum that some metal did displaced it and if it does, won't it cause the aqua regia to turn more and more acidic and eventualy attack my Copper and ionize it or the Copper will be coated in time with Platinum before the aqua regia starts to ionize it ?

i honestly don't know, maybe yes, but the platinum solution will be depleted

you should dissolve some platinum in aqua regia (nitric acid and hydrochloric acid 1:3) and evaporate the excess acid of course. the electrolysis should produce HCl, and maybe some chlorine and hydrogen at the electrodes if the voltage is not set right. copper won't be dissolved by HCl, especially at the cathode (reduction not oxidation)

Thank you so much Bruh :P I'll try it this month and notify you how it goes. I'm stuned how after many hours you're the only person that gave some knowlege on it, anyway, have a nice day Sir :P
