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

EMF depends on molarities of acids used

B

`pH` of 0.1 M `HCl` and 0.1 M `CH_(3)COOH` is same

C

the temperature is constant

D

acids used in two compartments are different

Text Solution

Verified by Experts

The correct Answer is:
B
(b)The EMF of the cell will not be zero because concentration of `H^(+)` ions in two electrolytic solution is different. Mean HCl is strong acid where, acetic acid is weak acid and gives different pH.
