S15. Ans.(a) 
Sol. Ni-Cd batteries contain nickel hydroxide as positive electrode plate, a cadmium hydroxide as negative electrode plate, and an alkaline electrolyte as separator. The chemical reaction which occurs in Ni-Cd battery is
                                                       2NiO (OH) + Cd + 2H2O  ↔2Ni(OH)2 + Cd(OH)2
