Aluminium Chloride Chemical Formula

The chemical formula for aluminium chloride is AlCl3. This compound consists of one aluminium ion (Al3+) and three chloride ions (Cl-). The aluminium ion has a 3+ charge because it has lost three electrons, while each chloride ion has a 1- charge because it has gained one electron. The resulting compound is held together by ionic bonds, which are electrostatic attractions between oppositely charged ions. Aluminium chloride is a white or yellowish solid that is highly soluble in water and other polar solvents. It is commonly used as a catalyst in organic chemistry reactions, as well as in the production of aluminum metal and other aluminum compounds.
