Question
The diagram shows an apparatus for the laboratory preparation of hydrogen chloride.
(i) Identify A and B
(ii) Write the equation for the reaction
(iii) How would you check whether or not the gas jar is filled with hydrogen chloride?
(iv) What does the method of collection tell you about the density of hydrogen chloride.

Solution
(i) A = conc. H2SO4 B = NaCl
(ii) \[\ce{NaCl + H2SO4 -> NaHSO4 + HCl}\]
(iii) When a rod dipped in ammonium hydroxide is brought near the mouth of the gas jar, dense white fumes of ammonium chloride are produced.
(iv) Hydrogen chloride is denser than air.
