Question

Why is it not possible to measure voltage of an isolated reduction half-reaction?

Answer 1

A redox reaction always consists of oxidation and reduction. In the cell, the electrode potential develops due to oxidation at anode and reduction at cathode. Therefore, it is not possible to measure the potential of an isolated half cell.

Hope this will help you

Answer 2

Explanation:

A Redox reaction always consisting of oxidation and reduction. In the cell the electrode potential developed due to oxidation at anode and reduction at cathode therefore it is not possible to measure the voltage of an isolated reduction half reaction .
