(a) Hydrochloric acid is prepared by this method.
(b) Sodium chloride and concentrated sulphuric acid are used as reactants.
(c) Empty flask is used to prevent back-suction.
(d) Concentrated sulphuric acid is used as a drying agent. It is because $H_{2} S O_{4}$ can help in easy drying of the moist hydrochloric acid.
(e) Inverted funnel is used to prevent back suction of water and to provide a larger surface area for the absorption of HCl gas.
