A chemical equation describes a reaction, indicating the reactants and products.

Oxidation is a type of reaction in which oxygen bonds to elements of the reactants.

Decomposition is a type of reaction in which a reactant compound breaks down into two or more products.

A reaction in which an insoluble salt forms from two solutions is called a precipitation reaction.

Three types of chemical reaction

Chemistry

In the Making salts unit, pupils will learn about the production of pure salts, concentration and strength of acids, and what makes acids acidic and how bases can neutralise them.

In the Atomic structure and periodic table unit, pupils learned about atoms, and how the periodic table is ordered, along with the history of both of their major discoveries.
