The reactions that take place at the cathode and the anode when molten NiBr 2 , AlF 3 and MnI 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 NiBr 2 is electrolyzed. The reaction taking place at cathode is, Ni 2 + + 2 e − → Ni The reaction taking place at anode is, 2 Br − → Br 2 + 2 e −
