Talk about the Hydrochloric acid

Do you know the Hydrochloric acid? Hydrochloric acid is a solution of hydrogen chloride (HCl) in water, which is a highly corrosive, strong mineral acid with many industrial uses. Historically called muriatic acid or spirits of salt, hydrochloric acid was produced from vitriol (sulfuric acid) and common salt.
The physical properties of hydrochloric acid, such as boiling and melting points, density, and pH depend on the concentration or molarity of HCl in the acid solution. They range from those of water at very low concentrations approaching 0% HCl to values for fuming hydrochloric acid at over 40% HCl.
Hydrochloric acid is a strong inorganic acid that is used in many industrial processes. The application often determines the required product quality. One of the most important applications of hydrochloric acid is in the pickling of steel, to remove rust or iron oxide scale from iron or steel before subsequent processing. Another major use of hydrochloric acid is in the production of organic compounds, such as vinyl chloride and dichloromethane for PVC. Hydrochloric acid is used for a large number of small-scale applications, such as leather processing, purification of common salt, household cleaning.
