Expert Answer:
Hydrogen is prepared in the laboratory by the action of dilute hydrochloric acid or dilute sulphuric acid on granulated zinc.
Reaction:
|
Metal + Dilute acid → Salt + Hydrogen Zn + 2HCl → ZnCl2 + H2 ↑ Zn + H2SO4 → ZnSO4 + H2 ↑ |
Collection of gas: Hydrogen gas is collected by downward displacement of water.
