What is Aluminium sulfate (Al2(SO4)3)?
Al2(SO4)3 is a chemical compound with chemical name Aluminium sulfate. It is also called Filter Alum or Dialuminum trisulfate. It is a white crystalline solid in its anhydrous form and in its solution form it appears as a colorless liquid. Both the forms are non-toxic and noncombustible. Aluminum sulfate is soluble in water but insoluble in ethanol. It is odorless and has a mildly astringent taste, sweet taste. On decomposing, it emits toxic fumes of sulfur oxides. The solution of aluminum sulfate is corrosive to aluminum. This compound is produced in the laboratory by adding aluminum hydroxide, to sulfuric acid.
