About this course

The Chemistry AS Level programme is a one-year course of study and should be taken in conjunction with two or three other subjects and the Welsh Baccalaureate. 

Based at our City Centre campus in Cardiff, this course is also available as an evening class.

The aims of this AS Chemistry qualification are to encourage students to:

  • Develop their interest in, and enthusiasm for Chemistry, including developing an interest in further study and careers in Chemistry
  • Appreciate how society makes decisions about scientific issues and how the sciences contribute to the success of the economy and society
  • Develop and demonstrate a deeper appreciation of the skills, knowledge and understanding of How Science Works
  • Develop essential knowledge and understanding of different areas of Chemistry and how they relate to each other

What you will study

The course covers two units:

UNIT CH1 – Controlling and Using Chemical Changes (in order to make things, produce energy and solve environmental problems).

This unit begins with some important fundamental ideas about atoms and the use of the mole concept in calculations. 

Three key principles governing chemical change are then studied:

  • The position of equilibrium between reactants and products
  • The energy changes associated with a chemical reaction
  • The rate at which reactions take place

These principles are then applied to some important problems in the fields of chemical synthesis, obtaining energy and the maintenance of the environment.

UNIT CH2 - Properties, Structure and Bonding

This unit looks at:

  • Chemical bonding
  • Forces between molecules
  • Shapes of molecules
  • Solubility of compounds in water
  • The Periodic Table
  • Trends in properties of the elements
  • Organic compounds and their reactions
