Question

How is hydrogen chloride prepared from sodium chloride?

✓

Answer

1. In the laboratory, hydrogen chloride, HCl is prepared by heating a mixture of NaCl and concentrated $H_2SO_4$.$NaCl + H _2 SO _4 \stackrel{420 K }{\longrightarrow} NaHSO _4+ HCl$
$NaHSO _4+ NaCl \stackrel{420 K }{\longrightarrow} Na _2 SO _4+ HCl$
2. Hydrogen chloride gas, is dried by passing it through a dehydrating agent like concentrated $H_2SO_4 $and then collected by upward displacement of air.
