HCl is an ionic compound that dissociates itself upon its addition to the solvent to form a solution. When it is in the solution it forms ions.


HCl  + H2O ---> H3O+  + Cl-

HCl forms hydronium ions (H3O+) and Chloride ions (Cl-)

some books simply show the dissociation as

HCl --> H+  + Cl-

**they omit the water in the equation.


The compound HCl has several names:

Hydrochloric acid

Hydrochloric acid gas


But its IUPAC official name is

Hydrogen Chloride
