Question

Consider two Group IV metal ions X^ 2+ and Y^ 2+ . A solution containing 0.01 M X^ 2+ and 0.01 M Y^ 2+ is saturated with H_2S. The pH at which the metal sulphide YS will form as a precipitate is _____ (Nearest integer) (Given : K_ sp (XS) = 1 10^ -22 at 25^ C, K_ sp (YS) = 4 10^ -16 at 25^ C, [H_2S]=0.1M in solution, K_ a1 K_ a2 (H_2S) = 1.0 10^ -21 , log2=0.30, log3=0.48, log5=0.70)
