This part of video only deals with concept of Hydrogen chloride gas thoroughly and next part will contain all remaining of this chapter i.e hydrochloric acid.


SYLLABUS 2025 :
Hydrogen Chloride
Hydrogen chloride: preparation of hydrogen chloride from sodium chloride; refer to the density and solubility of hydrogen chloride (fountain experiment); reaction with ammonia; acidic properties of its solution.
• Preparation of hydrogen chloride from sodium chloride; the laboratory method of preparation can be learnt in terms of reactants, product, condition, equation, diagram or setting of the apparatus, procedure, observation, precaution, collection of the gas and identification.
• Simple experiment to show the density of the gas (Hydrogen Chloride) –heavier than air.
• Solubility of hydrogen chloride (fountain experiment); setting of the apparatus, procedure, observation, inference.
• Method of preparation of hydrochloric acid by dissolving the gas in water- the special arrangement and the mechanism by which the back suction is avoided should be learnt.
• Reaction with ammonia
• Acidic properties of its solution - reaction with metals, their oxides, hydroxides and carbonates to give their chlorides; decomposition of carbonates, hydrogen carbonates, sulphides, sulphites.
• Precipitation reactions with silver nitrate solution and lead nitrate solution.
