The ability of a substance to dissolve in a particular solvent creating a solution; how well a solute dissolves in a solvent.

An ionic compound, usually formed by neutralisation of an acid by a base.

When a substance dissolves in a liquid, it is described as soluble in that liquid.

An insoluble solid formed when two solutions react together.

When a substance does not dissolve in a liquid, it is described as insoluble in that liquid.

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.
