It is a very hygroscopic colourless solid that is soluble in water and polar organic solvents. Tetramethylammonium chloride is a major industrial chemical, being used in such processes as hydrofracking.In the laboratory, it has fewer synthetic chemical applications than quaternary ammonium salts containing longer N-alkyl substituents, which are used extensively as phase-transfer catalysts.t is a very hygroscopic colourless solid that is soluble in water and polar organic solvents.

Calcium chloride can serve as a source of calcium ions in an aqueous solution, as calcium chloride is soluble in water.This property can be useful for displacing ions from solution.For example, phosphate is displaced from solution by calcium:he anhydrous form of calcium chloride may also be used for this purpose and can provide a measure of the moisture in concrete. Calcium chloride is used in swimming pool water as a pH buffer and to adjust the calcium hardness of the water.
