The process where a precipitate is formed.

An insoluble solid formed when two solutions react together.

Formed when a substance is dissolved in water.

A way of describing a substance that will not dissolve in a particular solvent.

A chemical test that confirms the presence of a substance, it does not tell you how much of the substance is present.

Chemical reactions: precipitation

Science

Characteristics of chemical reactions

Conservation of mass and balanced symbol equations

Chemical reactions: oxidation

Chemical reactions: combustion

Chemical reactions: decomposition

In the Acids and Bases unit, pupils will build on their understanding of chemical reactions to learn about the properties of acids, bases, alkalis, and the neutralisation reaction.

In the Atoms, Elements and Compounds unit, pupils learned about atoms, elements, and compounds and how particles reorganise in a chemical reaction.

This unit covers the conservation of mass in changes of state and chemical reactions, including atom rearrangement. It also focuses on representing reactions with formulae and equations, exploring combustion, decomposition, and displacement, and distinguishing chemical from physical changes.
