Question

(ii) Calculate the emf of the following cell at 298 K:

Al(s)/Al3+ (0.15M)//Cu2+(0.025M) /Cu(s)

(Given Eo

(Al3+/Al) = -1.66 V, Eo

(Cu2+/Cu) = 0.34V, log 0.15 = -0.8239, log 0.025 = -

1.6020)​

Answer 1

Al(s)/Al3+ (0.15M)//Cu2+(0.025M) /Cu(s)

(Given Eo

(Al3+/Al) = -1.66 V, Eo

(Cu2+/Cu) = 0.34V, log 0.15 = -0.8239, log 0.025 = -

1.6020)
