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

`pH` of `0.1 M HCl` and `0.1 M CH_(3)COOH` are not same

B

acids used in two compartments are different

C

the temperature is constant

D

emf depends on molarities of acids used

Text Solution

Verified by Experts

The correct Answer is:
A
It is a kind of concentration cell. The concentration of `H^(+)` ions in two half cell is different because `HCl` is a strong electrolyte while `CH_(3)COOH` is a weak electrolyte.
