Generally produced by treating cadmium solution with a soluble sulfide, it is a bright yellow pigment known as cadmium yellow, which is used in high-grade paints and artist’s pigments because of its colour stability and resistance to sulfur and oxidation. 65 Prop 65 NSRL Category Cadmium sulfide 1306-23-6 Carcinogen - Carcinogen U.S. State Right-to-Know Regulations Component MassachusettsNew Jersey Pennsylvania Illinois Rhode Island Cadmium sulfide X X X X - U.S. Department of Transportation Reportable Quantity (RQ): N To find more Manganese(II) sulfide information like chemical properties, structure, melting point, boiling point, density, molecular formula, molecular weight, physical properties and toxicity information. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite, but is more prevalent as an impurity substituent in the similarly structured zinc ores sphalerite and wurtzite, which are the major economic sources of cadmium. Cadmium Sulfide is also used in the production of solar cells where it is used as a buffer layer in the manufacture of CIGS (Copper -Indium-Gallium-Selenide) solar cells. Cadmium sulfide is the inorganic compound with the formula CdS. Solubility product constant (K sp) (or the solubility product) is the product of the molar concentrations of the constituent ions, each raised to the power of its stoichiometric coefficient in the equilibrium equation.For instance, if a compound A a B b is in equilibrium with its solution Cadmium sulfide is used as a pigment in the chemical industry; for manufacturing of photoresistors, optical-electronic pairs, … This chemical compound is yellow in color and is a semiconductor, by conductivity.

Alternative name for solubility equilibrium is solubility product constant. The solubility equilibrium is varies depending on the temperature. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite, but is more prevalent as an impurity substituent in the similarly structured zinc ores sphalerite and wurtzite, which are the major economic sources of cadmium. Calcium sulfate is used in electroplating, vacuum tubes, fluorescent screens, analytical chemistry, as a fungicide and as a chemical intermediate to produce cadmium containing pigments and stabilizers. Cadmium sulphide is not soluble in water but soluble in cold diluted HCI or sulphuric acid.
