$AgCN \rightleftharpoons Ag ^{+}+ CN ^{-}$

$K_{ sp }=\left[ Ag ^{+}\right]\left[ CN ^{-}\right]=6 \times 10^{-17}$

$Ni ( OH )_{2} \rightleftharpoons Ni ^{2+}+2 OH ^{-}$

$K_{ sp }=\left[ Ni ^{2+}\right]\left[ OH ^{-}\right]^{2}=2 \times 10^{-15}$

ધારો કે $\left[ Ag ^{+}\right]= S _{1},$ તો $\left[ CN ^{-}\right]= S _{1}$

ધારો કે $\left[ Ni ^{2+}\right]= S _{2},$ તો $\left[ OH ^{-}\right]=2 S _{2}$

$S _{1}^{2}=6 \times 10^{-17}, S _{1}=7.8 \times 10^{-9}$

$\left( S _{2}\right)\left(2 S _{2}\right)^{2}=2 \times 10^{-15}, S _{2}=0.58 \times 10^{-4}$

$Ni ( OH )_{2}$ $AgCN$ કરતાં વધારે દ્રાવ્ય છે.
