I'm working on etching al using this as etchant though I have no clue what the balanced equation is and have not been able to find it. I'm not a chemist though I have had a few semesters of college chem. Never took inorganic and would appreciate some advice on where to look for info and stoicheometry of the reaction. I have been looking both on the web and through journals with no luck, other than I think the CuCl2 does the etching and I thing the HCl is the for ph reasons, though that is just based on some experiments, and a reaction I saw online between Al and the CuCl2 without the HCl.
Thanks
