Explanation:
Hydrochloric acid is prepared by dissolving hydrogen chloride in water. Hydrogen chloride can be generated in many ways, and thus several precursors to hydrochloric acid exist. The large-scale production of hydrochloric acid is almost always integrated with the industrial scale production of other chemicals

Answer:
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.
