Calcium chloride (chemical formula: CaCl2) is a white or slightly yellow solid inorganic compound, belonging to the category of salts. It is a typical ionic halide and widely used in various fields due to its high solubility, hygroscopicity, and dehydration. According to its hydration form, it exists in different physical forms, with the most common being dihydrate (CaCl2 · 2H2O). Its high solubility allows it to quickly dissolve in water, releasing a large amount of heat, making it very useful in applications that require rapid heating or drying. In addition, calcium chloride is often used in salt water, road deicing agents, and desiccants used in refrigeration equipment.
