A voltaic cell is based on the reaction between Ag^+ and Ni(s) producing Ag(s) and Ni^2+?

Write the anode and cathode half reactions. include phases of all species in the chemical equation.

Cathode:

Anode:

Write a balanced cell reaction. Include the phases of all species.

1 Answer

  • anode = oxidation

    Ni –> Ni 2+ + 2e-

    cathode = reduction

    2(Ag+ + 1e- –> Ag)…..the 2 will balance the electrons

    Ni(s) + 2Ag+(aq) –> Ni 2+(aq) + 2Ag(s)
