Cell Potential

Q. For the cell shown, the measured cell potential Ecell is -0.3533 V at 25C Pt| H2(g, 0.709 atm) | H+ (aq, ? M) || Cd2+ (aq, 1.00 M) | Cd(s) The balanced reduction half reactions for the cell, and their respective standard reduction potential values, Eo, are 2H+ + e- -> H2(g) Eo = 0.00 V Cd2+(aq) + 2e- -> Cd(s) Eo = -0.403 V. Calculate the H+ concentration.
