An aqueous solution of a metal bromide MBr2 of 0.05M is saturated with H2S. What is the minimum pH at which MS will precipitate? Given Ksp of MS = 6.0 × 10−21. Concentration of saturated H2S = 0.1M (K1 of H2S = 10−7 and K2 = 1.3 × 10−1C)
An aqueous solution of a metal bromide MBr2 (0.05 M) is saturated with H2S. What is the minimum pH at which MS will precipitate? Ksp for M S = 6.0 × 10−21 : concentration of saturated H2S = 0.1 M : K1 = 10−7 and K2 = 1.3 × 10−13 for H2S.
