Hydrochloric acid

                                   Hydrochloric acid

Hydrochloric acid has the chemical formula HCl. It is used in our chemistry labs . It is corrosive and should be handled with care.
The acid can be found naturally occuring in the stomachs of many animals as a relatively weak solution. Excess hydrochloric acid in the stomach may cause dyspepsia. 
Hydrochloric acid does not contain any organic molecules , hence is regarded as a mineral acid. It is an aqueous solution of hydrogen chloride , which when in a saturated form contains about 43 % of hydrogen chloride. The aqueous solution is a strong electrolyte.
It disassociates to give H + and Cl - ions. Ionization is so much complete that the acid is considered as strong acid. Since it is a corrosive acid , it can be used to clean the metal surfaces. It is also a strong electrolyte, proton donor and also an acid.
