Question
During electrolysis of aqueous NaBr with inert electrodes, 0.112 L of Br₂ gas (STP) is produced at the anode. How many coulombs were passed? (F = 96500 C/mol)
Explanation
Anode: 2Br⁻ → Br₂ + 2e⁻ . 1 mol Br₂ (22.4 L) requires 2F. Moles = (0.112/22.4) = 0.005 mol , Charge = 0.005 × 2 × 96500 = 965 C .
