SATHEE: Redox Reactions And Electrochemistry Ques 610

Redox Reactions And Electrochemistry Ques 610

Question: The reduction potential (in volt) of a hydrogen electrode set up with a $2 \times 10^{- 2} M$ aqueous solution of a weak mono basic acid $(K_{a} = 5 \times 10^{- 5})$ at one atmosphere and $25^{\circ} C$ is

Options:

A) +0.09

B) +0.18

C) $- 0.09$

D) $- 0.18$

Show Answer

Answer:

Correct Answer: D

Solution:

[d] $2 H^{+} + 2 e^{-} \overset{}{\to} H_{2}$ $E_{c e l l} = 0.06, l o g [H^{+}] = 0.06 \times l o g \sqrt{K_{a} C}$ $= 0.06 \times l o g 10^{- 3} = - 0.18 V$
