Question: A solution of Sn 2+ is to be electrolyzed to reduce the Sn 2+ to Sn(s). Calculate the cathode potential (versus S.H.E.) needed to reduce

A solution of Sn²⁺ is to be electrolyzed to reduce the Sn²⁺to Sn(s). Calculate the cathode potential (versus S.H.E.) needed to reduce [Sn²⁺] to 1.0 × 10^-8 M if no concentration polarization occurs. What would be the potential versus S.C.E. instead of S.H.E.? Would the potential be more positive or more negative if concentration polarization occurred?
