Aluminum Sulfate (Al₂(SO₄)₃·xH₂O) is a white or slightly off-white crystalline flake that is highly soluble in water. It is one of the most widely used aluminum compounds and plays a critical role in water treatment, paper manufacturing, and other industrial applications. Aluminum sulfate is commonly referred to as "alum" in its hydrated form, although technically "alum" refers to a broader group of double sulfate compounds.
