Preparation of Hydrogen
Hydrogen gas is prepared in the laboratory by the action of dilute hydrochloric acid or dilute sulphuric acid on granulated zinc.
Zn + 2HCL → ZnCL₂ + H₂↑
Zn + H2SO₄ → ZnSO₄ + H₂↑
Granulated zinc is commercial zinc obtained from molten zinc. It contains impurities like copper which have a slight catalytic effect on the reaction and speeds up the reaction.
