Which of the following is the correct value of EMF of a following concentration cell?
`Cu|Cu^(2+)(0.01M)||Cu^(2+)(0.1M)|Cu` at `25^(@)C`

A

0.0295V

B

0.295V

C

29.5V

D

0.00295V

Text Solution

Verified by Experts

The correct Answer is:
A
`E=(2.303RT)/(nF)-"log"(C_(2))/(C_(1))`
`E=(0.059)/(n) "log"(C_(2))/(C_(1))=(0.59)/(2)"log"(0.1)/(0.001)`
`therefore E=0.0295V`,
