Hey as per your demand here I am providing you details of HCL as HCL is Hydrochloric acid

State of 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.

History of HCL
It was historically called acidum salis, muriatic acid, and spirits of salt because it was produced from rock salt and green vitriol and later from the chemically similar common salt and sulfuric acid
Free hydrochloric acid was first formally described in the 16th century by Libavius.
Later, it was used by chemists such as Glauber, Priestley, and Davy in their scientific research.

Uses
The uses of HCL is Converting insoluble amines into hydrochlorides is a common way to make them water-soluble. This characteristic is particularly desirable for substances used in medications
The European Pharmacopoeia lists more than 200 hydrochlorides as active ingredients in medications
These hydrochlorides, compared to free bases, may more readily dissolve in the gastrointestinal tract and be able to be absorbed into the bloodstream more quickly.
In addition, many hydrochlorides of amines have a longer shelf-life than their respective free bases
