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.

Hello Friends,
Here is Your answer
Hydrogen is prepared in the lab by the action of acids on metal's dilute. Sulphuric acid is added to granulated zinc. Zinc sulphate or zinc chloride is formed in solution and the hydrogen that is evolved is collected over water in a trough.
