Question

Why it is impossible to obtain the electrode potential for a single electrode?

Answer 1

It is not possible to measure the absolute potential of a single electrode because neither the oxidation nor the reduction reaction can occur by itself.

Answer 2

$<b><i>$Why it is impossible to obtain the electrode potential for a single electrode?

• It is due to the fact that neither by itself the oxidation occurs nor the reduction occurs .

• Experimentally, the absolute value of single electrode can't be determined, because independently half-cell reaction cannot occur.

• It is only possible to determine the difference between the electrode potentials of any two half-cell reactions.
