Q:

In case of a standard hydrogen electrode

A) absolute electrode potential is not zero	B) absolute electrode potential is zero
C) both absolute and standard electrode potential values are zero	D) electrode potential is zero only at 25 deg C

Answer & Explanation Answer: A) absolute electrode potential is not zero

Explanation:

The Standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials. Its absolute electrode potential is estimated to be 4.44 ± 0.02 V at 25 °C, but to form a basis for comparison with all other electrode reactions, hydrogen's standard electrode potential (E0) is declared to be zero volts only at 298.
