At `25^(@)C, {:(Ag+I^(-)rarr,AgI+e,,E^(@) =0.152V),(Agrarr,Ag.^(+)+e,,E^(@) =- 0.80V):}`
The `log K_(sp)` of `AgI` is: `((2.303RT)/(F)=0.059)`

A

`-8.12`

B

`+8.612`

C

`-37.83`

D

`-16.13`

Text Solution

Verified by Experts

The correct Answer is:
D
`E_(I^(-)//AgI//Ag)^(@) = E_(Ag^(+)//Ag)^(@)+0(0.059)/(1)logK_(sp_(AgI))`
`-0.152 = + 0.8 + (0.059)/(1)logK_(sp_(AgI))`
`:. log K_(sp_(AgI)) = -16.13`
