Chemical reactions of acids with metals and metal carbonates

Concentration of solutions

pH scale and indicators

Solubility rules

Making a pure dry sample of a soluble salt

Adapting a multistep chemical procedure for making a pure dry salt

Change in pH: practical

In the Electrolysis unit, pupils will build on their understanding of chemical reactions to explore the process of electrolysis and its applications.

In the Acids and Bases unit, pupils learned about the properties of acids, bases, and alkalis, and the reactions between them to form salts and water.

This unit explores empirical formulae, balanced chemical and ionic equations, gas identification, acid reactions, and pH as a measure of hydrogen ion concentration. It covers separation techniques and focuses on planning experiments, accurate measurements, safety, and communicating findings.
