Introduction
Name: Sulfuric acid
CAS No: 7664-93-9
Molecular Formula: H2SO4
Synonyms: Hydrogen sulfate
Sulfuric acid is one of the most active binary inorganic acids, which can react with most metals. Sulfuric acid with high concentration has strong water absorption. When mixed with water, it releases a lot of heat energy. It is highly corrosive and oxidizing and should be used with caution. It is an important industrial raw material.

Application
Sulfuric acid is mainly used in industry and agriculture.
1. Industrial field
Sulfuric acid can be used in metallurgy and metal processing; petroleum industry; chlor-alkali industry; inorganic salt industry; water treatment; dyestuff; chemical fiber, etc. In addition, many inorganic acids such as phosphoric acid, boric acid, chromic acid, hydrofluoric acid and chlorosulfonic acid; organic acids such as oxalic acid and acetic acid also need sulfuric acid as raw material.
2. The field of agriculture
Sulfuric acid can be used to improve calcareous soil with high PH value and lake water; it can also be used in the production of fertilizers and pesticides.
