The reactions that take place at the cathode and the anode when molten KF , CuCl 2 and MgI 2 are electrolyzed. Concept introduction: The non-spontaneous reaction takes place in an electrolytic cell in which there occurs conversion of electrical energy into chemical energy and this is used for the electrolysis of a metal. The electrolytic cell involves a cathode and an anode, both dipped into an electrolytic solution having both the positive and negative ions. To determine: The reactions that take place at the cathode and the anode when molten KF is electrolyzed. The reaction taking place at cathode is, K + + e − → K The reaction taking place at anode is, F − → 1 2 F 2 +e −
