Answer:
Hydrogen is prepared in the laboratory by the action of the dilute hydrochloric acid or dilute sulphuric acid on granulated zinc.
Use of Granulated Zinc.
Reaction:
Collection of Gas: Hydrogen gas is collected by downward displacement of water.
Answer:
In the laboratory, dihydrogen gas is prepared by taking zinc granules in a 500 ml flask.
To this, dilute HCl or dilute sulphuric acid is added through a thistle funnel.
Dihydrogen gas is released and the gas is collected by the downward displacement of water because it is a gas lighter than water
