A cell consists of a Sn⁴⁺|| Sn²⁺half-cell and a Fe³⁺ || Fe²⁺.If the Sn⁴⁺|| Sn²⁺ half-cell standard cell functions as the cathode,what is the standard reduction potential for the cell?

Question

Quizplus · Accepted Answer

The standard reduction potential for Sn⁴⁺/Sn²⁺ is +0.15V and for Fe³⁺/Fe²⁺ is +0.77V. Since Sn⁴⁺/Sn²⁺ is the cathode, the cell potential is E°(cathode) - E°(anode) = 0.15V - 0.77V = -0.62V.
