How will you prepare hydrochloric acid in laboratory?
Advertisements
उत्तर
Hydrochloric acid cannot be prepared by mixing hydrochloric acid gas directly in water, as it leads to back suction. A complete set-up of apparatus for the preparation of hydrochloric acid in the laboratory is shown in the given figure.
Hydrogen chloride gas prepared by the reaction of sodium chloride and sulphuric acid is passed to an inverted funnel arrangement through an empty flask. An inverted funnel connected to the HCl gas supply is placed in a beaker so that the rim of the funnel just touches the surface of the water in the beaker. HCl gas enters through the delivery tube, fills the mouth of the funnel, and then dissolves in water. In this way, we get hydrochloric acid in the beaker.
