Module 3 - The periodic table


Module 3: The Periodic Table

In addition to the aims of the scheme, this module provides candidates with a knowledge and understanding of chemical ideas that underpin the study of inorganic chemistry:

Practical Skills are assessed using OCR set tasks.

The practical work suggested below may be carried out as part of skill development. Centres are not required to carry out all of these experiments:

* Reactions of some Group 2 metals with oxygen and water.
* Action of water on Group 2 oxides and testing pH of resulting solutions.
* Thermal decomposition of Group 2 carbonates.
* Halogen displacement reactions.
* Testing for the presence of halide ions in solution using silver nitrate.
