What this unit aims at

This theme focuses on enabling children to know about one gas- Hydrogen and that it is an important constituent of several compounds. It is found in acids and organic compounds. It acts as a fuel which makes its study useful.

Your child should be able to

  • describe the preparation of hydrogen from electrolysis of water
  • prepare hydrogen in the lab. using zinc and acid
  • describe properties and uses of hydrogen
  • correlate concepts of oxidation and reduction with addition and removal of oxygen or removal and addition of hydrogen

Key concepts in this unit

  • Preparation of hydrogen, from water – electrolysis (Introduction to terms electrode, electrolyte, electrolysis - detailed process not required).
  • Preparation of hydrogen in the laboratory.
  • Preference of zinc as the metal to be used (with reasons).
  • Choice of dilute acids (other than dil. nitric acid).
  • Bosch’s process.
  • Properties and uses of hydrogen.
  • Oxidation and Reduction.
