Which of the following expression(s) represent the voltage of cell at 298 K :
Ag (s) | AgI (saturated solution)||Ag 2 C 2 O 4 (saturated solution) | Ag(s)
A
E cell = 0.0592 log 
B
E cell = 0.0592 log 
C
E cell = 0.0592 log 
D
E cell = 0.0592 log 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(b, d)
The given cell is concentration cell :
Ag ⎯→ (Ag + ) LHE + e
(Ag + ) RHE + e ⎯→ Ag
Net reaction : (Ag + ) RHE ⎯→ (Ag + ) LHE
E cell = 0 – 0.0592 log 
= 0.0592 log 
E cell = 0.0592 log 
In AgI solution, [Ag + ] = K sp (AgI) 1/2
In Ag 2 C 2 O 4 solution [Ag + ]
= 2 × 
= 
= [2 K sp (Ag 2 C 2 O 4 )] 1/3
