उत्तर
A platinised platinum foil is in contact with pure hydrogen gas at 1 atmosphere pressure in a solution of H+ (more accurately, H3O+) ions at a concentration of 1 mol L−1 to create a standard hydrogen electrode. Consequently, a typical hydrogen electrode can be shown as:
\[\ce{Pt H2_{(g)} (1 atm) | H+ (1 mol L^{-1})}\]
