In my project I need to study the rate of oxidation of [(NH3)5 Co S2O3]Cl to form [(NH3)5 Co S2O5]Cl by means of some oxidants.
Some of the oxidants like Oxone, peracetic acid and magnesium bis(monoperoxyphthalate) hexahydrate work but some others like hydrogen peroxide or tert butyl hydroperoxide don’t work.
What is the reason?
[(NH3)5 Co S2O3]Cl + 2 CH3CO3H = [(NH3)5 Co S2O5]Cl
