The electrochemical equivalents of two substances are E1 and E2. The current that must pass to depos — Electrochemistry Chemistry Question

💡 Solution & Explanation

Mass deposited $m = Z \times I \times t$, where Z is the electrochemical equivalent (given here as E1 and E2). For the same mass and time, $E_1 I_1 = E_2 I_2$. Rearranging this gives $I_1 / I_2 = E_2 / E_1$. Therefore, correct answer is B.
