FBC0025 5. A voltaic cell is constructed as follows: One electrode compartment consists of cadmium strip placed in a solution of Cd(NO3)2, and the other has a nickel strip placed in a solution of NiSO4. The overall cell reaction is as follows: a Cd (s) + Ni2+ (aq) → Cd2+ (aq) + Ni (s) a) Write the half-reactions that occur in the two electrode compartments. b) Which electrode is the anode, and which is the cathode? c) Indicate the signs of the electrodes. d) Do electrons flow from the cadmium electrode to the nickel electrode or from the nickel to the cadmium? e) In which directions do the cations and anions migrate through the solution?
