An electrochemical cell is set up as: Pt; 
(1 atm) 
HCl (O. 1 M) 
CHCOOH 
; Pt. The e.m.f. of this cell will not be zero, because
A
acids used in two compartments are different
B
e.m.f depends on molarities of acids used
C
the temperature is constant
D
of 0.1 M 
and 0.1 M 
is not same.
Text Solution
Verified by ExpertsThe correct answer is:
D
Since it is a concentration cell and the concentration of ions in two electrolyte solutions 
HC1 and 
) are different, therefore e.m.f. of this cell will not be zero.
