    Aluminum Sulfate

    Aluminium sulfate is a salt with the formula Al₂(SO₄)₃. It is soluble in water and is mainly used as a coagulating agent in the purification of drinking water

    Aluminum sulfate is white or off-white crystals or powder. It is not volatile or flammable. It has a low pH when combined with water making it capable of burning skin or corroding metal, is water soluble, and able to hold water molecules. When added to alkaline water, it forms aluminum hydroxide, Al (OH)3, as precipitate. It can be found naturally in volcanoes or mining waste dumps.

    The list of uses of aluminum sulfate is very long and includes bug killers for the garden, adding bulk to paper sheets in paper manufacturing, and a foaming agent in fire extinguishers. Water purification plants depend on aluminum sulfate to remove impurities. The chemical reaction between it and contaminates causes the contaminates to solidify and be filtered out. Sodium aluminum sulfate is found in baking powder, self-rising flour, and cake and muffin mixes. It is used in multiple industries serving a wide variety of purposes.
