The solubiltiy product of silver iodide ...

The solubiltiy product of silver iodide is `8.3 xx 10^(-17)` and the standard potential (reduction) of `Ag,Ag^(+)` electrode is `+0.800` volts at `25^(@)C`. The standard potential of `Ag,AgI//I^(-)` electrode (reduction) from these data is

A

`-0.30V`

B

`+0.15V`

C

`+0.10V`

D

`-0.15V`

Text Solution

Verified by Experts

The correct Answer is:
D
`0 =(E_(c)-E_(A)) -(0.0591)/(1)K_(sp)`
`E_(C) =- 0.80 - 0.0591 (-17 +log 8.3)`
`=- 0.80 +0.950 =- 0.15 V`
