Question

What maximum ph must be maintained in a saturated solution of h2s to precipitate?

Answer 1

A saturated solution of H 2S in water has concentration of approximately 0.10 M. What is the pH of this solution and equilibrium concentrations of H 2S, HS -and S 2-? Hydrogen sulphide is a diprotic acid and its dissociation constants are K a1 = 9.1 x 10 -8, K a2 = 1.3 x 10 -13 mol L -1 respectively.
