Characteristic
Potassium perchlorate is the inorganic salt with the chemical formula KClO4. Like other perchlorates, this salt is a strong oxidizer although it usually reacts very slowly with organic substances. This, usually obtained as a colorless, crystalline solid
Chemical formula:KClO4
Molar mass:138.55 g/mol
Appearance:colourless/ white crystalline powder
Density:2.5239 g/cm3
Melting point:610 °C (1,130 °F; 883 K);decomposes from 400 °C
Solubility in water:0.76 g/100 mL (0 °C);1.5 g/100 mL (25 °C);4.76 g/100 mL (40 °C);21.08 g/100 mL (100 °C)
Solubility product (Ksp):1.05·10−2
Solubility:negligible in alcohol;insoluble in ether
Solubility in ethanol:47 mg/kg (0 °C);120 mg/kg (25 °C)
Solubility in acetone:1.6 g/kg
Solubility in ethyl acetate:15 mg/kg
Refractive index (nD):1.4724
Crystal structure:Rhombohedral
Application
Potassium perchlorate is used in ammunition percussion caps, explosive primers, fireworks and propellants. It acts as a solid rocket propellant. It is also used as an oxidizer in colored pyrotechnic compositions and flash powder. It is used as an antithyroid and involved in the treatment of hyperthyroidism. The mixture of anthracene and sulfur with potassium perchlorate is used for generating black smoke signaling.
