Value of log ksp for AgI

Question

Given the data at 25°C Ag + I-–> AgI + e, E° =0.152, Ag–> Ag^+ + e, E°=-800. What is the value of log KSP for AgI?

Answer 1

The correct answer is -16.13

(i) Ag →Ag⁺+ e⁻ E^∘= −0.800V

(ii) Ag + I⁻ → Agl + e⁻  E^∘ =0.152V

(I) - (II) we have AgI → Ag⁺ + I⁻

E^∘=−0.952V
