Sulfuric Acid

Sulfuric acid (H₂SO₄) is a strong, highly corrosive acid with a wide range of industrial applications. It is a colorless, oily liquid that is soluble in water and exothermic when mixed with water. Sulfuric acid is one of the most important industrial chemicals, used in the production of fertilizers, chemicals, and various other products.

  • Physical Properties

    Colorlessto slightly yellow, oily liquid.
    Boiling point: 337°C (639°F); Melting point: 10°C (50°F).
    High density and strong hygroscopic nature, meaning it can absorb water from the air. pH level close to 0 in concentrated form, making it extremely acidic and corrosive

    Chemical Properties

    It is a strong acid and can react violently with water, releasing heat.
    Sulfuric acid is a powerful dehydrating agent, able to remove water from many substances.
    It can react with metals like zinc and iron to release hydrogen gas.
    It can dissolve many substances, including metals, ores, and organic materials

    Common Uses

    Fertilizer Production: Sulfuric acid is primarily used in the manufacture of phosphate fertilizers like superphosphate and ammonium phosphate.

    Chemical Manufacturing: It is involved in the production of chemicals such as sulfuric acid salts, detergents, and synthetic resins.

    Petroleum Refining: Sulfuric acid is used in petroleum refining for alkylation to produce high-octane gasoline.

    Metal Processing: It is used in pickling metals, removing rust and scale from metal surfaces.

    Water Treatment: Sulfuric acid is used to neutralize alkaline substances in wastewater treatment.
