Question

The standard reduction potential of Ag⁺ /Ag electrode at 298 K is 0.799V. Given that for AgI, K_sp = 8.7 × 10^–17, evaluate the potential of Ag⁺ /Ag electrode in a saturated solution of AgI. Also calculate the standard reduction potential of I^– electrode. 

Answer 1

In the saturated solution of AgI, the half cell reactions are

For above cell reaction
