Read the Assertion and Reason below and choose the correct option. — Electrochemistry Chemistry Question

💡 Solution & Explanation

Depositing 1 mole of Ag (from Ag^+) requires 1 Faraday of charge, while 1 mole of Cu (from Cu^2+) requires 2 Faradays. Thus, Statement I is true. The differing atomic masses of the two metals make Statement II factually true. However, the difference in electrical charge required stems from their different valencies (n-factors), not their atomic masses. Thus, Statement II does not explain Statement I. Therefore, correct answer is B.
