Potassium bromide is a colorless crystalline or white powder inorganic substance with the chemical formula KBr and a relative molecular mass of 119.00. It has a strong salty taste, is slightly hygroscopic, and turns yellow when exposed to light. Potassium bromide has a high solubility in water. 1g of potassium bromide can be dissolved in 1.5ml of water, and the aqueous solution is neutral. Its relative density is 2.75 (25°C), its melting point is 730°C, and its boiling point is 1435°C. Potassium bromide has a certain irritation and is mainly used as an analytical reagent and developer, and is also used in the pharmaceutical industry. It has important applications in spectral analysis, spot analysis of copper and silver, polarographic analysis of indium, cadmium,etc. In addition, potassium bromide is also used in the photosensitive material industry, such as the manufacture of photographic films, developers, film thickeners, toners, and color photo bleaching agents. In medicine, potassium bromide is used as a sedative. The physical and chemical properties of potassium bromide make it an important material in many fields, especially in spectral analysis and the pharmaceutical industry.
