Question

The Ksp of AgI is 8.5 × 10-17. Find the solubility of AgI in M

Answer 1

..............AgI ==> Ag^+ + I^-

I.............solid........0.........0
C............solid........x..........x
E.............solid........x...........x
Ksp = 8.5E-17 = (Ag^+)(I^-)
Substitute the E line into Ksp expression and solve for x = solubility in Mols/L
