Cadmium Sulfide Distributor of cadmium sulfide. In qualitative analysis, sulfide precipitating is done in two ways due to solubility of different metal sulfide's are different. Cadmium Sulfide is a crystalline solid used as a semiconductor and in photo optic applications. The solubility equilibrium is varies depending on the temperature. Answer to: Calculate the solubility of cadmium sulfide, CdS, in mol / L, given the K_{sp} value as 8.0 times 10^{-27}. Solubility. First, solubility (in g/L) of CdS: Cadmium (II) sulfide dissociates in water according to the following equation: CdS(s) ↔ Cd^2+(aq) + S^2-(aq) According to this balanced equation, one mole of CdS produces one mole of cadmium ions and one mole of sulfide ions. Cadmium sulfide is a yellow solid. Section 1: Identification .
