Physical Properties of Hydrogen Chloride:
(i) Hydrogen chloride is a colourless gas with a sharp irritating smell.
(ii) It turns damp litmus paper red.
(iii) It is about 1.25 times denser than air.
(iv) It is highly soluble in water. Because of its great solubilitySolubility is the maximum amount of a substance (called the solute) that can dissolve in a given amount of another substance (called the solvent) at a specific temperature and pressure, to... More, it fumes in moist air .
(v) It dissolves in non-polar solvents like chloroform and toluene.
(vi) In an aqueous solutionA solution in which the solvent is water is referred to as an aqueous solution. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For... More the compound is extensively dissociated into a hydroxonium ion (H3 O + ) and chloride ion (Cl– ); in dilute solutions, the dissociation is essentially complete. Thus, hydrochloric acid is a strong acid.
(vii) It does not support combustion.
Fountain Experiment:
Fountain experiment is used to demonstrate the solubility of hydrogen chloride gas.
Experiment Demonstration:
Fill a dry round-bottomed flask filled with dry Hydrogen chloride gas. Fix a two-holed rubber cork on the mouth of the round-bottomed flask. Fix a jet tube through one hole and a dropper, with a few water drops, through the other hole. Now put the other end of the jet tube in a container containing blue litmus solution.
Inject a few drops of
