This is the compilation of all SL terminologies and equations in each chapter that students must know. Some definitions are indeed asked in real IB exams, and others are terms students need to understand in order to absorb concepts more effectively. It also provides an overview of what each chapter is focusing on. Having this by your side when studying IB chemistry would be extremely helpful to see the entire syllabus just with terminologies.
