Ni-cad batteries are rechargeable and are commonly used in cordless appliances. Although such batteries actually function under basic conditions, imagine an electrochemical cell using the setup below.
Cd2+(aq) + 2 e– → Cd (s) Eº = – 0.40 V
Ni2+(aq) + 2 e– → Ni (s) Eº = – 0.25 V
What is E° for the cell?
