LiCl and MgCl2 both are soluble in ethanol.
Alcohol forms hydrogen bonding, and it also has a covalent character, so it is a polar solvent. Due to the polar nature, lithium chloride and magnesium chloride are soluble in polar solvent alcohol. Lithium chloride has a sufficient covalent character because of greater polarisation.
- Lithium chloride is mainly used to produce lithium metal by electrolysis of a LiCl/KCl melt at 450 °C (842 °F).
- Magnesium chloride is used to treat or prevent magnesium deficiency (lack of natural magnesium in the body).
