Question
How can you increase the reduction potential of an electrode.
Solution
The reduction potential of an electrode can be increased by adding a small amount of electrolyte to the half cell containing the electrode. The reduction potential of an electrode is directly proportional to the concentration of positive ions. Hence the increase in the concentration of cations results in an increase of reduction potential of an electrode and vice-versa. For example, the reaction of Zn - Cu cell is
An increase in the value of [Cu2+] derives the reaction more to the right (according to Le-Chatelier’s principle) resulting in higher values of A cathode.
