Question

meant of standard hydrogen electrode?​

Answer 1

Answer:

it is just a standard through which electrode potential of other elements are calculated.

Answer 2

The standard hydrogen electrode is the standard measurement of electrode potential for the thermodynamic scale of redox potentials. The standard hydrogen electrode is often abbreviated as SHE or may be known as a normal hydrogen electrode (NHE).

2 H+(aq) + 2 e- → H2(g) at 25 °C.
