potassium iodideAlso known as gray iodine, with a molecular formula of KI and a molecular weight of 166, it has slight deliquescence and turns yellow when left for a long time or when exposed to light. It is soluble in water, ethanol, and glycerol, with a melting point of 680 ℃ and a boiling point of 1420 ℃, and a density of 1.2924. Its aqueous solution is neutral or slightly alkaline and can dissolve iodine. Potassium iodide is like a "versatile hand", serving as both a "messenger" for transmitting activity in pharmaceutical synthesis, a "guardian" for protecting health in food fortification, and a "ruler" for precise laboratory analysis.

potassium iodideMainly used as a commonly used reagent for volumetric analysis of iodometric method. In haploid breeding, culture media such as Berlides, modified White, MS, and RM are prepared. Fecal testing, photography, pharmaceuticals, etc. In the laboratory, potassium iodide is widely used in iodometric titration, redox reaction indicators, and complexing agents. It is a routine experiment for water quality testing, food analysis, and other purposesimportantReagents. Potassium iodide is often added to traditional films and photosensitive emulsions to adjust their photosensitive performance. Food and feed additives, as iodine fortifiers, are used to prevent iodine deficiency disorders and ensure public health. Industrial applications also have important uses in electroplating, catalyst preparation, and synthesis of liquid crystal materials.

potassium iodideStorage: Potassium iodide is prone to moisture absorption and deliquescence. It should be stored in a dry, sealed brown glass bottle or plastic bucket lined with a plastic bag to avoid contact with air moisture. It is recommended to store in a cool, ventilated, and dark place, with a temperature controlled below 30 ℃. Do not mix with strong oxidants to prevent violent reactions. It is recommended to wear laboratory gloves, goggles, and masks during operation to avoid direct contact with the skin or inhalation of dust.
