Q.
The increasing order of $Ag ^{+}$ion concentration in
I. Saturated solution of $AgCl$
II. Saturated solution of $AgI$
III. $1 \,M \,Ag \left(( NH )_{3}\right)_{2}^{+}$in $0.1 \,M\, NH _{3}$
IV. $1 \,M \,Ag ( CN )_{2}^{-}$in $0.1 \,M \,KCN$
Given:
$K _{ sp } $ of $ AgCl =1.0 \times 10^{-10}$
$ K _{ sp } $ of $ AgI =1.0 \times 10^{-16} $
$ K_{ d } $ of $ Ag \left(( NH )_{3}\right)_{2}^{+}=1.0 \times 10^{-8}$
$ K _{ d } $ of $ Ag ( CN )_{2}^{-}=1.0 \times 10^{-21}$
