What is reduction potential of hydrogen gas electrode when pure hydrogen gas is at 1 atmospheric pressure and platinum electrode is in contact with HCl solution of PH 1 at 298 K ?
- A -0.1184 V
- B -0.0592 V
- C -0.0296 V
- D -0.592 V
Answer & Solution
Correct Answer
(B) -0.0592 V
Step-by-step Solution
Detailed explanation
\( \text{pH} = 1 \Rightarrow [H^+] = 10^{-1} \text{ M} \) \( E = E^\circ - \frac{0.0592}{n} \log \frac{P_{H_2}}{[H^+]^2} \)
