Characteristic
Potassium sulfate (in British English potassium sulphate (SOP), also called sulphate of potash, arcanite, or archaically known as potash of sulfur) is the inorganic compound with formula K2SO4. It is a white water-soluble solid.
Chemical formula:K2SO4
Molar mass:174.259 g/mol
Appearance:White solid
Odor:odorless
Density:2.66 g/cm3
Melting point:1,069 °C (1,956 °F; 1,342 K)
Boiling point:1,689 °C (3,072 °F; 1,962 K)
Solubility in water:111 g/L (20 °C);120 g/L (25 °C);240 g/L (100 °C)
Solubility:slightly soluble in glycerol;insoluble in acetone, alcohol, CS2
Magnetic susceptibility (χ):−67.0·10−6 cm3/mol
Refractive index (nD):1.495
Crystal structure:orthorhombic
Application
Potassium sulfate is used in the production of fertilizers (i.e. providing potassium and sulfur), potassium alum, potassium carbonate and glass. In analytical chemistry, it is used in the determination of nitrogen by the Kjeldahl method and protein in foodstuffs. Also, it is used in the electrostatic effects on pKa values of amino acid residues in the staphylococcal nuclease. It is used in the separation of protein through electrophoresis and also serves as a laboratory reagent.
