Question Question 5(2018)
Name the acid used for the preparation of - hydrogen chloride gas in the laboratory. State why this particular acid is preferred to other acids.
Conc. H2SO4 is used for the preparation of hydrogen chloride gas in the laboratory.
As conc. H2SO4 is non-volatile and has a high boiling point, therefore, it displaces the volatile hydrogen chloride from the salt sodium chloride. Hence, conc. H2SO4 is used as a reactant in the laboratory preparation of HCl from sodium chloride
