I. Physical and Chemical Properties: The molecular formula of sulfuric acid is H2SO4, and its relative molecular weight is 98.08. It is a colorless and transparent liquid with a density of 1.84 g/cm³ at room temperature and a boiling point of 337°C. Sulfuric acid has strong corrosive and oxidizing properties and can react with many substances, including organic and inorganic compounds and metals. Sulfuric acid is highly soluble in water and releases a large amount of heat, which can raise the temperature of the water.

III. Uses: Sulfuric acid is a very important chemical reagent and is widely used in laboratory and industrial production. In the laboratory, sulfuric acid is used for acid-base titration, dehydration of substances, preparation of catalysts, and so on. In industrial production, sulfuric acid is used to produce fertilizers, paper, chemical fibers, synthetic materials, and more.
