उत्तर
Chlorides react with concentrated sulphuric acid on warming to liberate hydrogen chloride.
The process requires two steps due to the presence of two replaceable hydrogen ions in H2SO4.
\[\ce{NaCl + H2SO4(conc.) ->[below 200^\circ C] NaHSO4 + HCl\uparrow}\]
\[\ce{2NaCl + H2SO4 ->[above 200°C] Na2SO5 + 2HCl}\]
