What is Standard Hydrogen Electrode (SHE) ? What are its applications ?
Answers
Answer:
Standard hydrogen electrode is the reference electrode that is used to calculate electrode potential of any electrode. It is also called as SHE or NHE. This apparatus consists of beaker having 1 molar HCL solution. In it, a sealed tube having platinum wire is dipeed.

Though its very hard to handle standard hydrogen electrode, but as we take its potential to be zero by convention, thus, we measure the other half cell potentials with respect to that. But it needs extreme care to handle this. Thus, nowadays we generally use calomel electrodes or sometimes quinhydrone electrodes according to our requirement.
