can i get help with this
a. What is the overall reaction when lead sulfide combines with
acid (H*)?
b. What is the value of the equilibrium constant (K) for the
combined
reaction?
c. What will the concentration of Pb2+ be at pH=3.25 when all of
these
equilibria are taken into account?
d. Heavy metals are often found as sulfide compounds, which
typically have
very very low solubility. Explain why acid mine tailings are able
to solubilize
several normally insoluble heavy metals. question information in the image

Consider the following equilibrium processes with associated constants at a given temperature: PbS(s) <--> Pb2+ (aq) + S² (aq) Kp-4.3 x 10-26 These are the acid dissociation constants for H₂S. H₂S(aq) <--> HS (aq) + H*(aq). K₁1-1.5 x 107 HS (aq) <--> S2 (aq) + H*(aq) Ka2 -1.80 x 10-12 In an acidic solution, such as acid mine tailings, one finds an increased amount of solubilized lead, as well as H₂S in the solution. ings with acid (4+1?
