Aluminum sulfate is commonly prepared in an industrial setting by reacting aluminum hydroxide, Al(OH) 3, with sulfuric acid, H 2 SO 4. This reaction results in the production of aluminum sulfate and water. Aluminum sulfate forms colorless crystals that are hygroscopic, meaning they readily absorb moisture from the air. It is soluble in water ...
