When you look at the IB Chemistry Subject Guide much of the first 19 pages or so is taken up with material which is essentially the same for all Group 4 subjects and chemistry really only comes into its own with the syllabus which starts on page 20. Quite helpfully the syllabus is actually given three times. It starts with a syllabus outline (see below), this is then followed by the syllabus content and finally the detailed syllabus is given which also contains guidance for the teacher.
Background and rationale
In the past (up until 1997) there was an IB Standard Level only subject called Applied Chemistry in addition to Higher Level and Standard Level Chemistry. Applied Chemistry was essentially chemistry and society and at one point several of us met to decide what basic understanding of chemistry a student needed if they were going to be ‘chemically literate’ and be able to apply their chemistry to the problems of society. We came up with eleven separate topics which formed the core of Applied Chemistry and essentially these are the core topics of today – the only real change is that one topic ‘States of Matter’ has been replaced by ‘Measurement and data processing’. Applied Chemistry had another major influence on today’s syllabus too –the current options originate from Applied Chemistry as in the past Chemistry at both Standard Level and Higher Level was just a theoretical subject with no options.
Current syllabusThe syllabus ouline given on pages 20 and 21 of the guide is a helpful summary as it also gives suggested times that should be spent on teaching each topic. These times are not mandatory and are only a rough guide. It is worth noting that the times do not include the practical work which may also be done on each topic. Apart from Topic 1: Stoichiometric relationships, the remaining ten topics are covered in greater depth to make up the Additional Higher Level material (AHL) (Topic 21 is called Measurement and analysis but follows on from the spectroscopy covered in Topic 11). The guide gives the core then the AHL. In some ways it is easy to see the core as Standard level and then the core and AHL together for Higher Level.

There are also four options. Each option takes up 15 hours of teaching time at Standard Level and 25 hours of teaching time at Higher Level. Both Standard and Higher Level students are expected to study just one of the four options.
Option A : Materials
Option B : Biochemistry
Option C : Energy
Option D : Medicinal chemistry
