What Is The Chemical Formula Of Aluminium Chloride Hexahydrate?

The chemical formula of aluminium chloride hexahydrate is AlCl3•6H2O. This formula indicates that one molecule of aluminium chloride (AlCl3) is associated with six water molecules (H2O), which are referred to as water of hydration or water of crystallization.

The dot between AlCl3 and 6H2O indicates that the two components are not chemically bonded, but rather held together by intermolecular forces. The number 6 in front of H2O indicates the number of water molecules associated with each molecule of AlCl3.

Aluminium chloride hexahydrate is a white or colorless solid that is highly soluble in water. It is commonly used as a catalyst in organic synthesis, as an electrolyte in batteries, and as a flocculating agent in water treatment.
