20. A galvanic (voltaic) cell is constructed froma half-cell containing a solid aluminum electrode dipped in a 1.0 M Al(NO3)3 solution and a half-cell containing a solid indium electrode in contact with a 1.0 M In(NO3)3 solution. The half-cells are linked by an external circuit (a wire) and by a KCl salt bridge. The cell generates a standard voltage of 1.32 V and the indium electrode is positive. The standard half-cell reduction potential for aluminum, E°(Al3*/Al), is listed in the...

When determining the relative reduction potentials of several electrode systems, why does it not matter what is chosen as a reference electrode? What action(s) is/are required to compare electrode potentials measured relative to different references? A galvanic cell is created according to the following cell notation: Al(s) | Al3+(1.0M) || Cu2+(1.0M) | Cu(s) Reduction Half Reaction E ̊ (volts) Al3+(aq) + 3e- -> Al(s) -1.66 Cu2+(aq) + 2e- -> Cu(s) 0.34 What is the overall cell potential?

In a galvanic cell, a spontaneous redox reaction occurs. However the reactants are separated such that the transfer of electrons is forced to occur across a wire. The resulting electricity is measured in volts (V) and is the sum of the potentials of the oxidation and reduction half-reactions: E^o cell = E^o red + E^o ox By reversing the reduction half-reactions, you get the corresponding oxidation half-reaction, for which E^o ox has the opposite sign of E^o red You can...
