Physical and Chemical Properties
Hydrochloric acid, such as boiling and melting points, density, and pH, depend on the concentration or molarity of HCl in the aqueous solution. They range from those of water at very low concentrations approaching 0% HCl to values for fuming hydrochloric acid at over 40% HCl

Application
1.Hydrometallurgy
Precipitation for rare metals
2.Organic Synthesis
For example, in the 180 ºC ~ 200 ºC  and mercury salts (such as HgCl2) as a catalyst ,under the conditions of hydrogen chloride and acetylene addition reaction, the formation of vinyl chloride, and then under the action of the initiator, polymerization of polyvinyl chloride
3.Bleaching and dyeing industry
For example, after cotton mercerizing , the residual alkali could be washed by hydrochloric acid. In the printing and dyeing process, some dyes do not dissolve in water, hydrochloric acid may change these dyes into soluble hydrochloride salt.
4.Metal cleaning
Steel parts,before electroplating, at first cleaning with caustic soda solution to remove oil, and bathing with hydrochloric acid.Remove all oil and metal oxide on its surface.
5.Food industry
Hydrochloric acid is used to hydrolyze starch to produce starch syrup
6.Production of Inorganic and organic drugs

Storage
Store in a cool, well ventilated warehouse. Storage temperature is less than 30ºC, and the relative humidity is less than 85%. Keep the container sealed. Keep separate from alkalis, amines, alkali metal and flammable or combustible substance and be careful not to place them together. The leakage emergency treatment facility and appropriate collecting containers should be available in the storage area.
