Question

describe the construction and working of standard hydrogen electrode. ​

Answer 1

Answer:

The standard hydrogen electrode consists of a platinum electrode coated with platinum black. The electrode is dipped in an acidic solution and pure hydrogen gas is bubbled through it. ... This implies that the pressure of hydrogen gas is one bar and the concentration of hydrogen ion in the solution is one molar.
