An electrochemical cell is shown below ...

An electrochemical cell is shown below `Pt, H_(2)(1 "atm")|HCl(0.1 M)|CH_(3)COOH(0.1 M)|H_(2)(1 "atm")`, The emf of the cell will not be zero, because

A

The pH of 0.1 M HCl and 0.1 M acetic acid is not the same

B

Acids used in two compartments are different

C

E.M.F. of a cell depends on the molarities of acids used

D

The temperature is constant

Text Solution

Verified by Experts

The correct Answer is:
A
The pH of 0.1 M HCl and 0.1 M acetic acid is not the same, because HCl is a strong acid so its pH is less and `CH_(3) COOH` is a weak acid, so its pH is more.
