प्रश्न
How are the following conversion brought about? Give equation and condition:
Sodium chloride to hydrogen chloride.
उत्तर
Sodium chloride to hydrogen chloride :
Sulphuric acid when reacts with sodium chloride it forms sodium bisulphate and hydrochloric acid because sulphuric acid when treated with salts of more volatile acids displaces more volatile acids.
