Solution

Hydrogen chloride:

  • Hydrogen chloride (HCl) is a colourless to slight yellow colour gas.
  • It is a corrosive and non-flammable gas.
  • When it is exposed to air, it forms dense white corrosive vapours.
  • It is heavier than air and has an irritating odour.
  • Hydrogen chloride (HCl) is soluble in water and forms hydrochloric acid (HCl)
  • Due to the electronegativity difference between the two elements, hydrochloric acid (HCl) becomes a polar molecule.
  • The other reason for solubility: it is a strong acid which ionizes to a high degree in the presence of water.
  • Conc. Sulphuric acid (H2SO4) is a hygroscopic agent which absorbs water from the air and becomes diluted and acts as a drying agent.

Therefore hydrogen chloride (HCl) gas which is highly soluble in water is dried by passing through Conc. Sulphuric acid (H2SO4).
