Hydrogen chloride gas on dissolving in water produces strong monobasic acid. Hydrochloric acid is formed.
- Hydrogen chloride gas is not directly absorbed in water because direct absorption leads to the back suction of water
- Hydrogen chloride (HCl) is a colourless gas that forms white fumes of hydrochloric acid when brought into contact with atmospheric humidity.
- When dissolved in water, the HCl gas dissociates and forms hydronium and chloride ions:
- HCl + H2O → H3O + + Cl–
- This solution is called hydrochloric acid
