The number of Faradays required to produce 1 g-atom of Mg from MgCl2 is — Electrochemistry Chemistry Question

💡 Solution & Explanation

1 g-atom of Mg corresponds to 1 mole of Mg. The reduction of Mg2+ is $Mg^{2+} + 2e^- \rightarrow Mg$. To produce 1 mole of Mg requires 2 moles of electrons, which is equivalent to 2 Faradays of electricity. Therefore, correct answer is B.
