Question

7. Two different electrolytic cells containing aqueous $AgNO_3$ and aqueous $CuSO_4$ are connected in series. The molar ratio of Copper to Silver deposited at their respective cathodes will be:

Prashant Kotian · Accepted Answer

Correct answer: A. By Faraday's Second Law, the equivalents deposited are equal. Eq(Cu) = Eq(Ag). Moles(Cu) = Moles(Ag) . Therefore, Moles(Cu) / Moles(Ag) = 1 / 2.
