Hey as per your demand here I am providing you details of Uses of Hydrochloric Acid

About HCL
Hydrochloric acid is a clear, colorless, highly pungent solution of hydrogen chloride (HCl) in water.
It is a highly corrosive, strong mineral acid with many industrial uses.
Hydrochloric acid is found naturally in gastric acid.
When it reacts with an organic base it forms a hydrochloride salt.

Uses of HCL
The leather tanning industry uses hydrochloric acid in the processing of leathers.
Hydrochloric acid is effectively used to regenerate ion exchangers.
The production of inorganic compounds for water treatment can require hydrochloric acid, including drinking water and wastewater.
Hydrochloric acid is used in to facilitate oil well acidizing in North Sea oil production.
Hydrochloric acid is used in the manufacturing of organic compounds like dichloroethane and vinyl chloride, which is used to manufacture PVC (Poly Vinyl Chloride).
It is used to effectively regulate the pH level of a wide variety of manufacturing processes including the production of drinking water, foods and pharmaceuticals.
Hydrochloric acid is necessary to lower the pH or total alkalinity of the water in swimming pools to optimal levels for swimmers.
This acid can be used in the salt purification process.
It is used in a specific process to 'pickle' steel. The process involves removing rust and scale from a steel coil or sheet with the help of a hydrochloric acid solution.

Production
Hydrochloric acid is prepared by dissolving hydrogen chloride in water.
Hydrogen chloride can be generated in many ways, and thus several precursors to hydrochloric acid exist.
