Cadmium Sulphate is an inorganic compound with Cd and SO₄ ions. It is found in a most common form called monohydrate CdSO₄.H₂O. the two other forms also exist of which one is anhydrous salt. All salts are colorless and water-soluble. Cadmium Sulphate sinks and mixes slowly in water at a moderate/room temperature. It serves as a fungicide and is also an intermediate chemical to produce stabilizers and pigments. It irritates the skin, damages the lungs, and chest pain when exposed for a long time. It occurs as a very rare mineral drobecite.

It is a hygroscopic compound that appears as a whitish crystalline solid. Its structure is monoclinic for hepta & octahydrate and orthorhombic for anhydrous form. It is an odorless solid.it is insoluble in ethanol but slightly soluble in methanol and ethyl acetate. When it is heated to decomposition, Cadmium Sulphate emits toxic fumes of cadmium oxide and Sulphur oxide.

CADMIUM SULPHATE HAS EXTENSIVE APPLICATIONS AS A CHEMICAL COMPOUND AS WELL AS A SALT.

• It serves as a pH regulating agent.
• It works as an accelerator in cement production.
• It is used as a fungicide.
• It is widely used in the electroplating of some metals. Normally electroplating of cadmium is done as to be used in electric circuits.
• It is mainly utilized for electrolytes in a Weston standard cell as well as a pigment in fluorescent screens.
• Cadmium Sulphate is a precursor to cadmium sulfide or other cadmium-based pigments.
