Question

How much will the reduction potential of a hydrogen electrode change when its solution initially at pH =0 is neutralised to pH =7 : (A) Increase by 0.059 V (B) Decrease by 0.059 V (C) Increase by 0.41 V (D) Decrease by 0.41 V

For H-electrode, R.P =-0.059 × pH -0.059 × 7=-0.41 V

Q. How much will the reduction potential of a hydrogen electrode change when its solution initially at $p H = 0$ is neutralised to $p H = 7$ :

Increase by 0.059 V

Decrease by 0.059 V

Increase by 0.41 V

Decrease by 0.41 V

For H-electrode, $R . P = - 0.059 \times p H$

$- 0.059 \times 7 = - 0.41 V$
