Redox Reactions And Electrochemistry Ques 58
Question: If hydrogen electrode dipped in 2 solution of $ pH=3 $ and $ pH=6 $ and salt bridge is connected the e.m.f. of resulting cell is [DPMT 2005]
Options:
A) 0.177 V
B) 0.3 V
C) 0.052 V
D) 0.104 V
Show Answer
Answer:
Correct Answer: A
Solution:
$ E_{cell}=-0.059\log \frac{{10^{-6}}}{{10^{-3}}}=-0.059\log {10^{-3}} $ $ =-0.059\times (-3)=0.177V $ .
