Q 2606823778.     A solution contains a mixture of `Ag^ + (0.1 0 M)` and `Hg^(2+) (0.10 M)` which are to be separated by selective precipitation. Calculate the maximum concentration of iodide ion at which one of them gets precipitated almost completely. What percentage of that metal ion is precipitated?

`K_(sp) : AgI= 8.5 xx 10^(-17), HgI_2 = 2.5 xx 10^(-26)`
