Question

(ii) Calculate the emf of the following cell at 298 K:
Al(s)/AP+ (0.15M)//Ni2+ (0.025M) /Ni(s)
(Given E.(Al3+ Al) = -1.66 V, E.(Ni2+ /Ni) = 0.25V, log 0.15 = -0.8239, log 0.025 = -1.6020)
(iii) Calculate AGº for above cell reaction.​

Answer 1

Explanation:

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

Al(s)/AP+ (0.15M)//Ni2+ (0.025M) /Ni(s)

(Given E.(Al3+ Al) = -1.66 V, E.(Ni2+ /Ni) = 0.25V, log 0.15 = -0.8239, log 0.025 = -1.6020)
