Calculate the standard cell potential for each of the following electrochemical cells.
Standard Electrode Potentials at 25 âC Reduction half-reaction Eâ(V) Ag+(aq)+eâ âAg(s) 0.80 Sn2+(aq)+2eâ âSn(s) -0.14 ClO2(g)+eâ âClO2â(aq) 0.95 I2(s)+2eâ â2Iâ(aq) 0.54 Ni2+(s)+2eâ âNi(s) -0.23 O2(g)+4H+(aq)+2eâ â2H2O(l) 1.23
1. 2Ag+(aq)+Sn(s)â2Ag(s)+Sn2+(aq)
2. 2ClO2(g)+2Iâ(aq)â2ClOâ2(aq)+I2(s)
3. O2(g)+4H+(aq)+2Ni(s)â2H2O(l)+2Ni2+(aq)
