States of Matter and Separation Techniques
The different states of matter, the arrangement and the energy of the particles in solids, liquids and gases.
How to separate various mixtures using techniques such as filtration, distillation and chromatography?
Atoms, Elements and Compounds
The structure of atoms, relative atomic masses and isotopes.
Formulae of elements and compounds, and relative formula masses.
Chemical bonding
How ionic, covalent and metallic bonds are formed?
How to draw dot-and-cross diagrams to represent bonding?
Structure of substances
How the properties of substances are related to the their structure and the kind of bonding they have?
Giant ionic structures, simple molecules, giant covalent structure, giant metallic structure.

Electrolysis
Properties of Group 1: The Alkali Metals, Group 7: The Halogens, Group 0: The Noble Gases
The vocabulary used in electrolysis and how the process works
How to work out what the products will be when doing electrolysis of ionic compounds when molten, and when in solution?
What are half-equations are also covered?
The chlor-alkali industry as a specific example of the use of electrolysis in industry. Electrolysis of brine.
Extraction and Uses of Metals
How to extract Aluminum and Iron?
Basic Calculations
Relative atomic mass, relative formula mass, percentage composition, empirical formula calculations, water of crystallisation.
Calculations involving Moles
The definition of the mole, converting masses, volumes and concentrations to moles, reacting quantity calculations, use of Avogadro's number, and calculations in electrolysis.


Rates of Reaction
Collision theory and how it enables us to predict how different conditions will affect the rate of a reaction.
Experimental methods to determine the rate of a reaction, and the role of catalysts.
Energy Changes and Calorimetry
Endothermic and exothermic reactions, and the process of bond breaking and bond making to calculate how large the energy change during a reaction will be.
Calorimetry: the practical method for measuring the energy changes that accompany reactions.
Acids, Bases and Salts
The nature of acids, alkalis, bases and salts.
What are the different acid reactions which are used to make soluble salts, and the precipitation reactions which are used to make insoluble salts?
Equilibrium and Industrial Processes
Reversible reactions, the idea of chemical equilibrium, and how conditions affect the position of equilibrium, before considering the Haber Process and the Contact Process.
How taking control of the equilibrium allows each of these processes to be optimised?
