Sulphuric acid, because of its low volatility can be used to manufacture more volatile acids from their corresponding salts.

                     2 \mathrm{MX}+\mathrm{H} 2 \mathrm{SO} 4 \rightarrow 2 \mathrm{HX}+\mathrm{M} 2 \mathrm{SO} 4(\mathrm{M}=\text { Metal and } \mathrm{X}=\mathrm{F}, \mathrm{Cl}, \mathrm{NO} 3)

Concentrated sulphuric acid is a strong dehydrating agent.Many wet gases can be dried by passing them through sulphuric acid, provided the gases do not react with acid.Hot concentrated sulphuric acid is not a moderately strong reducing agent but an oxidising agent.
