In 1886, Moissan was the first to prepare F2 by the electrolysis of F- ions. He electrolyzed KF dissolved in pure HF. No water was present, so only F- ions were available at the anode. What was the produced at the cathode? Write the half equations for the oxidation and reduction reactions, and then write the net cell reaction.
