For the electrochemical cell: Ag|AgCl(...

For the electrochemical cell:
`Ag|AgCl(s)|KCl(aq)||AgNO_(3)(aq)|Ag`
The overall cell reaction is

A

`Ag^(+)+KClrarrAgCl+K^(+)`

B

`Ag^(+)+Cl^(-)rarr+(1)/(2)Cl_(2)`

C

`AgClrarrAg^(+)+Cl^(-)`

D

`Ag^(+)+Cl^(-)rarrAgCl`.

Text Solution

Verified by Experts

The correct Answer is:
D
For metal insoluble salt anion half cell
`Ag.AgCl|Cl^(-)(aq)rarrAgCl(s)+e^(-)`
The half cell reaction for cathode is
`Ag^(+)(aq)+e^(-)rarrAg(s)`
`therefore ` Over all reaction is
`Ag^(+)(aq)+Cl^(-)(aq)rarrAgCl(s)`
