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.

Solubility rules

Combined science

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.

Making salts

Physical activity and equipment requiring safe use

The ability of a substance to dissolve in a solvent.

The speed at which a substance dissolves.

The ability of a substance to conduct electricity.

The temperature at which a substance melts.

A substance that evaporates from a liquid.

A solid that forms and settles out of a liquid mixture.

Which ionic compounds are generally soluble?

What is an exception to the solubility of chlorides?

A reaction where two soluble salts form an insoluble solid.

A reaction where two liquids combine to form water.

A reaction where energy is released as light.

They help predict the speed of reactions.

They help predict which compounds will dissolve or form a precipitate.

They help predict whether a gas will be formed.

They help determine the energy released in a reaction.

How can solubility rules help in predicting reactions?

A substance composed of positively and negatively charged ions.

A type of metal that is highly conductive.

A compound formed by sharing electrons equally.

An arrangement of elements by their atomic number.

The states of matter of various substances.

A change in colour without forming new substances.

A process where substances combine or break apart to form new substances.

A physical change in the shape of an object.

Characteristics observed during a chemical reaction.

Traits that describe the reactivity of a substance.

Features of a substance that can be measured.

A substance with a fixed composition that can't be separated into its components
