3. Answer the following in brief
ix. It is impossible to measure the potential of a single electrode. Comment.
Answer:-
Every oxidation reaction must be accompanied by a reduction reaction.
The occurrence of solely oxidation or reduction is not feasible.
In a galvanic cell, oxidation and reduction happen simultaneously.
The potential associated with the redox reaction can be experimentally determined. To measure this potential, two electrodes are combined where the redox reaction occurs.
Therefore, it is not possible to measure the potential of a single electrode.
