Web13 Apr 2024 · Ksp = [Fe2+] ⋅ [S2−] Notice that for every 1 mole of iron (II) sulfide that dissociates in aqueous solution, you get 1 mole of iron (II) cations and 1 mole of sulfide anions. This means that the equilibrium concentrations of the two ions will be equal to the molar solubility of the salt. Therefore, you can say that Ksp = 6.31 ⋅ 10−10 ⋅ 6.31 ⋅ 10−10
