Sodium Sulphate Anhydrous (500g)


Sodium sulfate anhydrous is a white crystalline compound used in detergents, paper, glass, and textiles manufacturing. It has a molecular weight of 142.04 g/mol, a 99% assay, and a pH of 7.0-9.5. Other specifications include low levels of chloride, iron, and heavy metals, a maximum loss on drying of 1.0%, and a bulk density of 800-1100 kg/m3.

Sodium sulfate anhydrous, also known as Glauber’s salt, is a white crystalline compound with the chemical formula Na2SO4. It is an inorganic salt that is highly soluble in water and has a melting point of 884°C. The anhydrous form of sodium sulfate does not contain any water molecules, whereas the hydrated forms include one, seven, or ten water molecules per sodium sulfate molecule.

Sodium sulfate anhydrous is commonly used in the manufacturing of detergents, paper, glass, and textiles. It is also used in the chemical industry as a laboratory reagent, in water treatment as a source of sulfate ions, and in the food industry as a thickening and anti-caking agent.
