A hydrogen gas electrode is made by dipping platinum wire in a solution of HCl of pH = 10 and by passing hydrogen gas around the platinum wire at one atm pressure. The oxidation potential of electrode would be?
Options
- A0.59 V
- B0.118 V
- C1.18 V
- D0.059 V
Correct answer
A. 0.59 V
Step-by-step solution
H 2 → 2 H + + 2 e - E o x i l = E o x i d 0 - 0.059 2 l o g 10 ( H + ) 2 P H 2 = 0 - 0.059 2 l o g 10 ( 1 0 - 10 ) 2 1 = 0.59 V
