Hydrochloric acid 01 (inorganic compound)

Dilute hydrochloric acid,commonly known as hydrochloric acid,is an aqueous solution of hydrogen chloride(HCl)gas with a solute of a strong acid.Hydrochloric acid has strong volatility,so when opening a container containing concentrated hydrochloric acid,acid mist can be seen above it,which is small droplets of hydrochloric acid produced by the combination of hydrogen chloride volatilization and water vapor in the air.Hydrochloric acid is a common chemical and raw material with many applications,including household cleaning,food additives,rust removal,leather processing,etc.The annual production of hydrochloric acid in the world is about 20 million tons.The general mass fraction of commercially available hydrochloric acid is 37%(about 12mol/L).Hydrochloric acid is not only an important product of salt chemical industry,but also an important raw material for the production of silicon materials.
