Lithium chloride (chemical formula: LiCl) is an alkali metal halide, a white, deliquable solid at room temperature. Due to the smaller ionic radius and higher hydration energy of lithium, the solubility of lithium chloride is much greater than that of other chlorides (83g/100mL, 20�°C). Its aqueous solution is alkaline. Lithium chloride is a sodium chloride type structure, in which the chemical bond is not a typical ionic bond, so it can be dissolved in many organic solvents, and ethanol, amines can form different admixtures. This property can be used to separate lithium chloride from alkali metal chlorides.
