प्रश्न
What property of conc. H2SO4 is made use of in the following case? Give an equation for the reaction in this case:
As a source of hydrogen by diluting it and adding a strip of magnesium.

उत्तर
Magnesium is present above hydrogen in the reactivity series, so sulphuric acid is able to liberate hydrogen gas by reacting with the magnesium strip.
\[\ce{Mg + H2SO4 -> MgSO4 + H2}\]
