A 0.10 M FeSO:(aq) solution is electrolyzed between a magnesium cathode and a platinum anode with a current density of 1.0 mA cm2. The hydrogen overpotential is 0.65 V. What will be the concentration of Fe2+ ions when evolution of H2 just begins at the cathode? Assume all activity coefficients are unity. (E°(Fe2+/Fe)= -0.44V)
