A nicd battery uses nickel and cadmium to produce a


A NiCd battery uses nickel and cadmium to produce a potential difference. Using these equations, answer the following questions.

I. 2NiO(OH) (s) + 2H2O (l) + 2 e- → 2Ni(OH)2(s) + 2 OH¯ (aq)

II. Cd (s) + 2OH¯ (aq) → Cd(OH)2 (s) + 2e¯

III. Cd (s) + 2NiO(OH) (s) + 2 H2O (l) → 2 Ni(OH)2(s) + Cd(OH)2(s)

Which equation best represents the reduction half-reaction?
