1 Fe2S3 2 Fe3 3 S2 the solubility product constant is given by Ksp Fe32 S23 now Fe2S3 2 Fe3 3 S2 let the molar solubility be s then Fe3 2s S2 3s now Ksp Fe32 S23 Ksp 2s2 3s3 Ksp 108 s5 we know that Ksp value of Fe2S3 is 14 x 1088 so 14 x 1088 108 x s5 s 10533 x 1018 so the molar solubility of iron III sulfide is 10533 x 1018 mol L 2 AgOH Ag OH Ksp Ag OH 2 x 108 now AgOH Ag OH let the molar solubility of AgOH be s then at equilibrium Ag s OH s now Ksp Ag OH Ksp s s Ksp See Answer
