1. A disproportionation reaction is a specific type of redox reaction in which an element from a reaction undergoes both oxidation and reduction to form two different products. The disproportionation reaction shown below occurs in basic solution. Balance this reaction using the half-reaction method. CIO2 → ClO, + CIO; 2. Write the half reactions for the anode and the cathode as well as the overall cell reaction in the following galvanic cells. Then, calculate E"cell using the tabulated values of standard reduction potentials.
