# Standard Electrode Potentials and Disproportionation

Given the following standard electrode reduction potentials,

ClO3- + 2H2O <- -> ClO- + 4OH- E° = +0.50V

ClO- + H2O + 2e- <- -> Cl- + 2OH- E° = +0.89V

Predict whether or not CLO- will disproportionate in alkaline solution to give Cl- and ClO3- according to the following reaction:

3ClO- -> 2Cl- + ClO3-

Show a calculation to support answer.

#### Solution Preview

This problem is based on adding two equations. First, you know two Cl- ions are formed. This means the second equation needs to be doubled. In redox problems, doubling the reaction does not double to potential. It will stay at 0.89 ...

#### Solution Summary

This solution combines two reduction potentials to create an electrochemical equation and then judges whether or not a reaction will occur based on this equation.
