You are making a galvanic cell using the following half reactions AgI(s) +eAg(s) + (aq) E= -0.15V MnO₂ (s) + 4H+ (aq) + 2e → Mn²+ (aq) + 2H₂O(1) E° = 1.23V (a) Give the cell notation for this cell. (b) What is the overall reaction? (c) What is the standard cell potential? (d) At what pH will the cell potential be 1.35 V if all other ion concentrations or 0.500 M?
