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 −

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box.
Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below.
Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first
stable product you expect to form in solution.
