Audited Supplier hydrochloric acid is an aqueous solution of hydrogen chloride (HCl) and is widely used in industry. Hydrochloric acid is a colorless and transparent liquid with a strong pungent odor and high corrosiveness. Concentrated hydrochloric acid (mass fraction of about 37%) is extremely volatile, so after the container containing concentrated hydrochloric acid is opened, the chlorinated hydrogen gas will volatilize, and combine with water vapor in the air to produce small hydrochloric acid droplets, so that acid fog appears above the bottle mouth. Hydrochloric acid is the main component of stomach acid, which promotes the digestion of food and protects against microbial infections. In the 16th century, Libarfius officially recorded the preparation of hydrogen chloride. Later, chemists such as Glauber, Priestley, and Davy also used hydrochloric acid in their research. During the Industrial Revolution, hydrochloric acid began to be produced in large quantities. In the chemical industry, hydrochloric acid has many important applications and plays a decisive role in the quality of products. Hydrochloric acid can be used for pickling steel and is also a chemical agent required for the large-scale preparation of many inorganic and organic compounds, such as vinyl chloride, the precursor of PVC plastics. Hydrochloric acid also has many small-scale uses, such as household cleaning, the production of gelatin and other food additives, descaling agents, and leather processing.
