Sulfuric Acid (Industrial Grade, Analytical Reagent Grade)

Product Name: Sulfuric Acid (Industrial Grade, AR Grade)

English Name: Sulfuric acid

Sulfuric acid (chemical formula: H₂SO₄) is the most important oxyacid of sulfur. Anhydrous sulfuric acid is a colorless, oily liquid that crystallizes at 10.36°C. It is commonly used in various concentrations of aqueous solutions, produced by the chamber process and the contact process. The former yields crude dilute sulfuric acid, generally with a mass fraction of around 75%; the latter produces pure concentrated sulfuric acid with a mass fraction of 98.3%, a boiling point of 338°C, and a relative density of 1.84.

Sulfuric acid is a highly reactive, dibasic inorganic strong acid that can react with many metals. Concentrated sulfuric acid has strong hygroscopic properties and can be used as a dehydrating agent, carbonizing materials containing carbohydrates such as wood, paper, cotton, linen fabrics, and biological tissues. When mixed with water, it releases a significant amount of heat. It is highly corrosive and oxidizing, requiring careful handling. As an important industrial raw material, it is used in the production of fertilizers, pharmaceuticals, pigments, detergents, storage batteries, and is widely applied in petroleum purification, metal smelting, and the dye industry. It is commonly used as a chemical reagent in organic synthesis, serving as a dehydrating and sulfonating agent.
