Properties of Aluminum Sulfate

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
