A solution is 0.0100 M in each of the metal ions in the following table:

Metal sulfide, Kspa FeS, Kspa = 6 x 10^2 NiS, Kspa = 8 x 10^(-1) PbS, Kspa = 3 x 10^(-7) CuS, Kspa = 6 x 10^(-16) HCl is added to the solution so that the H3O concentration is 0.300 M. H2S gas is bubbled through the solution to attain a H2S concentration of 0.100 M. Predict which of the sulfides... show more Metal sulfide, Kspa
FeS, Kspa = 6 x 10^2
NiS, Kspa = 8 x 10^(-1)
PbS, Kspa = 3 x 10^(-7)
CuS, Kspa = 6 x 10^(-16)

HCl is added to the solution so that the H3O concentration is 0.300 M. H2S gas is bubbled through the solution to attain a H2S concentration of 0.100 M. Predict which of the sulfides precipitate under the given conditions
