Welcome to Study IB Diploma Chemistry



Who is this site for?

This is a revision site for International Baccalaureate Diploma Programme chemistry students. It is written specifically for the Standard Level and Higher Level chemistry specifications for the IBDP. It may also be useful for any students studying chemistry.

What is a Beta version?

This website is under construction; it is not complete, so we have called it a beta version. Our aim is to have it completed, for all SL and HL core topics, as a revision site before the May 2020 IB examinations session.

At the moment the following topics are Beta phase complete:

Atomic Structure, Stoichiometric relationships and Equilibrium

And the following topics will be Beta phase complete by the end of January:

Energetics / Thermochemistry

What is here?

Each topic has a number of sub-topics that are 'children' of the topic page. These sub-topic pages contain the chemistry.

You will find these sections below on each of the sub-topic pages:


This section highlights particularly important things to remember and gives you revision tips for the topic.

Key Terms

This section contains flash cards that you should use to ensure that you understand the vocabulary of the topic. Asterixed (*) definitions are those that you must learn to recall - you may be asked for the precise definition in an examination.

Video Tutorials

This section contains video tutorials on particularly challenging or important concepts/tasks within the topic.

Revision Cards

This section contains concise revision notes completely covering the sub-topic.


This section contains a multiple choice quiz that attempts to cover all of the key understandings/concepts/tasks required for this sub-topic. Many of the questions are written in the style of an IB examination paper, but because the questions seek to cover all of the key understandings/concepts/skills, some questions are more challenging than those that you will find on a multiple choice IB examination paper and will require the use of a calculator (a calculator is not allowed in the IB multiple choice examination - paper 1).

More questions are available in the Question Bank where you can create a random or custom quiz.
