QUESTION #72 Precipitation and pH Dependence
Consider two Group IV metal ions X²⁺ and Y²⁺. A solution containing 0.01 M X²⁺ and 0.01 M Y²⁺ is saturated with H₂S. The pH at which the metal sulphide YS will form as a precipitate is ____ (Nearest integer) (Given : Kₛₚ(XS) = 1 × 10⁻²² at 25°C, Kₛₚ(YS) = 4 × 10⁻¹⁶ at 25°C, [H₂S] = 0.1 M in solution, Kₐ₁ × Kₐ₂(H₂S) = 1.0 × 10⁻²¹, 2 = 0.30, 3 = 0.48, 5 = 0.70)
