Represent a cadmium-copper cell.Give the electrode and net cell reaction If the standard
reduction potentials of Cd and Cu are – 0.40V and 0.34V respectively. Calculate the stad emf of the
ndar cell
In a cadmium-copper cell, the cadmium electrode acts as the anode and the copper electrode acts as the cathode.
The net cell reaction is:
Cd(s) + Cu2+(aq) -> Cd2+(aq) + Cu(s)
The standard potential of the cell can be calculated using the formula:
Ecell = Ecathode - Eanode
Ecell = 0.34V - (-0.40V)
Ecell = 0.74V
Therefore, the standard emf of the cell is 0.74V.
