Given the data 25^(@) C, Ag+ I^(-) to...

Given the data `25^(@) C`,
`Ag+ I^(-) to AgI+e^(-)` , `E^(@) = 0.152V`
`Ag to Ag^(+) + E(-)`, `E^(@) = - 0.800V`
What is the value of` K_(sp) ` for AgI?

A

(-8.12)

B

(+8.612)

C

(-37.83)

D

(-16.13)

Text Solution

Verified by Experts

`E_(IAgI//Ag)^(0)=E_(Ag+//Ag)^(0)(0.059)/(1)logK_(AP_(AgI))`
`-0.152=0.8+(0.059)/(1)logK_(AP_(AgI))`
`logK_(SP_(AgI))=-16.13`
