Q. Astandard 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
Explanation
(b)
Standard hydrogen electrode (SHE) is reference electrode. It is used to determine the electrode potential of any half cell. The electrode potential of any standard hydrogen electrode is arbitrarily taken as zero.
