Question
14. What quantity of electrical charge in Faradays is required for the complete conversion of 1 mole of $MnO_4^-$ to $Mn^{2+}$?
Answer: C
💡 Solution & Explanation
The conversion of $MnO_4^-$ to $Mn^{2+}$ changes the oxidation state of Manganese from +7 to +2. This requires 5 moles of electrons per mole of reactant, meaning 5 Faradays of charge.
