Write short note on working of SHE.

Answer»

It can behave as anode and cathode depending upon another electrode taken.

(a) When it acts as anode reaction will be :-

H₂ ---> 2H⁺ + 2e

Representation will be :- Pt, H₂ (1atm.) / H⁺ ( 1M)

(b) 2H⁺ + 2e^- -----> H₂

Representation will be :- / H⁺ ( 1M) / H₂ (1atm.), Pt
