A solution is a mixture of 0.06 M KI. AgNO 3 solution is being added drop by drop till AgCl starts precipitating (Ksp AgCl = 1*10 -10 and Ksp AgI = 4*10 -16 ). The concentration of Iodide ion at this stage will be nearly equal t :- a.4*10 -5 M b.2.4*10 -7 M

conc. of [Ag]+= ksp of AgCl/ conc. of Cl- common ion      = 1x 10^-10 / 0.06 , then
 conc. of[ I -]ion =  Ksp of AgI   / conc. of [Ag]+common ion = 4x10^-16 x 0.06 / 10^_10     = 2.4 x 10^-7 M.
