b. Here are the equations, this time with their equilibrium constants. What is the equilibrium constant value for the correct overall equation from part a? PbS(s) <--> Pb²+(aq) + S²-(aq) Ksp = 4.3 x 1027 These are the acid dissociation constants for H₂S. H₂S(aq) <--> HS (aq) + H*(aq). Ka1 = 1.1 x 10-7 HS (aq) <--> S2(aq) + H+(aq) Ka2 = 1.12 x 10-12 ○ 5.5 x 10-8 ○ 2.25 x 10-6 O 3.48 x 10-8 ○ 3.91 x 10-20 5.30 × 10-46
