Answer to Question #1940 in Inorganic Chemistry for reza nemati

Question

Hi
I have a question about Fenton process with copper formulation and I need your kindly assistance and guidance if possible . My question is that why the bivalent copper salts are used in fenton reactions for hydroxyl radical producing, while monovalent copper catalyze hydrogen peroxide to producing free radicals as following reaction.
Fenton reaction:
Cu(i) + H2O2 = Cu(ii) + HO* + OH-
& For example Why we use CuCl2 and we not use CuCl directly?.
Thank you for your patience and your kind answer

Answer 1

May be due to the fact that CuCl₂ is more soluble in water than CuCl.
