Aluminium Chloride Molecular Formula

The molecular formula of aluminium chloride is AlCl3. This means that one molecule of aluminium chloride is made up of one atom of aluminium (Al) and three atoms of chlorine (Cl).

Aluminium chloride is an inorganic compound that is commonly used as a catalyst in organic reactions, particularly in the production of plastics and petroleum products. It is also used in the manufacture of dyes, medicines, and other chemicals.

The structure of aluminium chloride is characterized by the formation of ionic bonds between the positively charged aluminium ion and the negatively charged chloride ions. The aluminium ion has a charge of +3, while each chloride ion has a charge of -1. This results in a total charge of zero for the compound.

In terms of its physical properties, aluminium chloride is a white or yellowish solid at room temperature and pressure. It has a melting point of 190.7°C and a boiling point of 180.8°C. It is highly soluble in water and forms a colorless solution that is acidic due to the hydrolysis of the compound into aluminium hydroxide and hydrochloric acid.

In summary, the molecular formula of aluminium chloride is AlCl3, which represents the composition of one molecule of the compound containing one atom of aluminium and three atoms of chlorine.
