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...

A certain half-reaction has a standard reduction potential =E0red−0.99V . An engineer proposes using this half-reaction at the cathode of a galvanic cell that must provide at least 1.20V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the cathode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the anode of this cell can have? If so, check the...
