Calculate the molar solubility of a hypothetical metal sulfide, MS, in a solution saturated with H2S at 25C. The pH of the solution is 3.44. Kspa for MS is 1.7 x 10-3.
I know that I need to use the pH to find the H3O+ concentration... and I am pretty sure the rxn is:
MS + 2H3O <-> H2S + M + 2H2O
But I am not sure what to do once I have the [H3O+]... Thanks!
