Preparation of Hydrogen Chloride

Muriatic acid is prepared by warming NaCl crystals with concentrated H2SO4 (Sulphuric acid).

NaCl+H2SO4→NaHSO4+HCl

Usually, most of the hydrogen chloride/hydrochloric acid that is formed is a co-product of some other chemical reactions. HCl is also formed by the chlorination of hydrocarbons.

Properties of Hydrogen Chloride

  • HCl is an uncoloured gas and has a pungent aroma.

  • Hydrochloric acid is the aqueous solution of hydrogen chloride.
  • HCl is soluble in water.
  • It liquefies at 189K to form a colourless liquid and freezes at 159k to form a white solid.
