Aluminium sulfate is a chemical compound with the formula Al2(SO4)3. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water and waste water treatment plants, and also in paper manufacturing
Aluminium sulfate 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 colourless liquid. Both the forms are non-toxic and non-combustible.
Aluminium sulfate is soluble in water but insoluble in ethanol. It is odourless and has a mildly astringent taste, sweet taste. On decomposing, it emits toxic fumes of sulphur oxides. The solution of aluminium sulfate is corrosive to aluminium. This compound is produced in the laboratory by adding aluminium hydroxide, to sulphuric acid
