Redox Reactions And Electrochemistry Ques 91

Question: The oxidation potential of a hydrogen electrode at pH = 10 and $ pH_1=1 $ [JIPMER 2000]

Options:

A) 0.059 V

B) 0.59 V

C) 0.00 V

D) 0.51 V

Show Answer

Answer:

Correct Answer: B

Solution:

$ E_{OP}=E_OP^{o}-\frac{0.059}{1}\log \frac{[{H^{+}}]}{{P_{H_2}}} $ \ $ [{H^{+}}]={10^{-10}};{P_{H_2}}=1atm $ ; $ E_{OP}=0.59V $ .
