DEMO ~TOPIC 02-HYDROGEN

HYDROGEN

Hydrogen is the lightest and the most abandonment element in the universe.

This means it is an element from which the sun and stars are made from.

LABORATORY PREPARATION OF HYDROGEN

Hydrogen can prepared in the laboratory by the following method;

The reaction of dilute hydrochloric acid and with zinc metal. When a zinc reacts with diluted Hydrochloric acid, zinc chloride and Hydrogen gas is produced.

Reaction: Zn(s) + 2HCl(l) → ZnCl₂(aq) + H2(g)

• Zinc +Hydrochloric acid → Zinc chloride + hydrogen gas

Hydrogen is a good reducing agent.
