Aluminum Chloride in Water
Upon dissolving aluminum chloride in water, hydrolysis occurs, yielding aluminum hydroxide and hydrochloric acid. This reaction is expressed as:

AlCl3 + 3H2O → Al(OH)3 + 3HCl

The resultant aluminum hydroxide may polymerize, generating distinct species. These aid coagulation and enhance flocculation during water treatment, eliminating particles and impurities. Hydrolysis yields hydrochloric acid, impacting solution acidity. Aluminum chloride’s water treatment efficacy hinges on concentration, pH, and water chemistry.
