In which of the following cells net cell reaction is :
Ag+ (aq) + Cl– (aq) ¾®AgCl (s)
A
Ag | AgCl (s) | KCl (aq) || NH4NO3 || AgNO3 | Ag
B
Ag | AgCl (s) | KCl (aq) | Ag
C
Ag | AgNO3 || NH4NO3 || KCl (aq) | AgCl | Ag
D
All of the above
Answer
Ag | AgCl (s) | KCl (aq) || NH4NO3 || AgNO3 | Ag
Explanation
Solution
Ag | AgCl (s) | KCl (aq) || NH4NO3 || AgNO3 | Ag Salt bridge
LHE reaction : Ag + Cl– ¾® AgCl (s) + e
RHE reaction : Ag+ + e ¾® Ag
Net reaction : Ag+ + Cl– ¾® AgCl (s)
