Lithium chloride is a chemical compound with the formula Li Cl.The salt is a typical ionic compound (with certain covalent characteristics), although the small size of the Li + ion gives rise to properties not seen for other alkali metal chlorides, such as extraordinary solubility in polar solvents (83.05 g/100 mL of water at 20 °C) and its hygroscopic properties.

Lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride. The nucleus of the lithium atom verges on instability, since the two stable lithium isotopes found in nature have among the lowest binding energies per nucleon of all stable nuclides .

This is particularly relevant when measurements are made on concentrated salt solutions. For example, a solvation number of 3 for a lithium chloride solution could be interpreted as being due to the equilibrium [Li(H 2 O) 4] + + Cl − ⇌ [Li(H 2 O) 3 Cl] + H 2 O. lying wholly in favour of the ion pair.
A simple absorption refrigeration system common in large commercial plants uses a solution of lithium bromide or lithium chloride salt and water. Water under low pressure is evaporated from the coils that are to be chilled. The water is absorbed by a lithium bromide/water solution.

The rate of dissolution will decrease substantially once it needs to penetrate through the pores of substance A in order to continue targeting substance B. [1] This penetration can often lead to dissolution of substance A, [1] or the product of more than one solute, [10] both unsatisfactory if specific leaching is desired.
