A standard hydrogen electrode has zero electrode potential because :

A

Hydrogen is easier to oxidise

B

This electrode potential is assumed to be zero

C

Hydrogen atom has only one electron

D

Hydrogen is the lightest element.

Text Solution

Verified by Experts

The correct Answer is:
B

Standard hydrogen electrode is a reference electrode. Potential of any half cell is calculated with respect to standard hydrogen electrode (SHE). Hence, electrode potential of SHE has been arbitrarily taken to be zero.
