Question

Define single electrode potential and explain its origin

Answer 1

An electrochemical cell consists of two half-cells. With an open-circuit, the metal electrode in each half-cell transfers its ions into solution. Thus an individual electrode develops a potential with respect to the solution. The potential of a single electrode in a half-cell is called the Single electrode potential.

EMF cell = EMF oxidation + EMF reduction
Thus anindividual electrode develops apotential with respect to the solution.
