Calculate standard cell potential for a cell having following reaction,

2Al_{(s)} + 3Ni^{2+} \longrightarrow 2Al^{3+} + 3Ni_{(s)}

( V, V)

(A)0.50 V
(B)1.41 VCorrect
(C)-0.50 V
(D)0.41 V

Answer: (B)

Solution

Al is oxidised (anode) and Ni is reduced (cathode). V. The standard potential is an intensive property, so the stoichiometric coefficients 2 and
