Answer the following.
How is hydrogen chloride prepared from sodium chloride?
Advertisements
उत्तर
1) In the laboratory, hydrogen chloride is prepared by heating sodium chloride (common salt) with concentrated sulfuric acid
\[\ce{\underset{\text{Sodium chloride}}{NaCl} + \underset{\text{Sulfuric acid (conc.)}}{H2SO4} ->[420 K] \underset{\text{Sodium hydrogen sulfate}}{NaHSO4} + \underset{\text{Hydrogen chloride}}{HCl}}\]
\[\ce{\underset{\text{Sodium hydrogen sulfate}}{NaHSO4} + \underset{\text{Sodium chloride}}{NaCl} ->[823 K] \underset{\text{Sodium sulfate}}{Na2SO4} + \underset{\text{Hydrogen chloride}}{HCl}}\]
2) HCl gas can be dried by passing it through concentrated sulfuric acid.
