FeS COS CdS Ksp 8.01x10-19 Ksp = 5.0×10-22 Ksp = 1.0x10-27 The sulfide concentration at which the metal begins to precipitate can be calculated from the solubility product. S²- + max = K SP M²+ The concentration of H* required to produce this [S2]max from a solution that has a total H₂S concentration of CH₂S can be calculated from K₁X K₁2×CH₂S al a2 [S²] Imax where Ka1 = 1.02x107 and Ka2 = 1.22× 10-13. Calculate the concentration of sulfide, S²- max, at which FeS would just begin to precipitate. (Assume that [Fe²+] = 0.01 M.) What pH would be required to produce this S² max What would be the concetration of Co²+ at this point? What would be the concetration of Cd²+ at this point? from a CH2S = 0.01 M solution?
