Is each of the following substances likely to serve as an oxidant or a reductant?

Answer 1

Oxidised substance:- HCHO Reduced Substance:- Cu2 + Reducing agent:- HCHO Oxidising agent:- Cu2+ Explanation:- Oxidising agent is a reagent which can increase the O.N. of an element in a given substance. Cu+ 2 helps HCHO to increase its oxidation state. The reduced substance is a reagent whose oxidation state has been decreased. Here, in this case, Cu+2 has + 2 oxidation state and the O.N. is reduced to + 1 as Cu+1 in the product side is present in + 1 O.N. The oxidised substance is a reagent whose oxidation state has been decreased. Carbon in HCHO is present in zero oxidation state which is increased to + 2 in HCOO-. Reducing Agent is a reagent which lowers the oxidation number of an element in a given substance. HCHO helps Cu+2 to decrease its oxidation state.

Answer 2

@ j. I don't see any questions. As far as I can tell the response is out of thin air.
