Write the equations describing the electrode reactions and t

Write the equations describing the electrode reactions and the net cell reaction for this electrochemical cell containing indium and cadmium:

In(s)|In3 (aq)||Cd2 (aq)|Cd(s)

Solution

anode: In(s) - 3e ---> In^3+(aq)

cathode: Cd^2+(aq) + 2e ---> Cd(s)

total equation:

2In(s) + 3Cd^2+(aq) ---> 2In^3+(aq) + 3Cd(s)
