IB Chemistry SL Notes

Aimnova offers free IB Chemistry SL revision notes for the first-exams-2025 syllabus, covering all six themes from Structure 1 to Reactivity 3. Each topic includes clear concept explanations, Lewis and VSEPR diagrams, reaction profiles and energy cycles, formula-first worked examples, spaced-repetition flashcards, and IB-style practice questions with AI feedback — no sign-up required to read the notes.

IB Chemistry SL is built on two big ideas across six themes: Structure (the particulate nature of matter, models of bonding and structure, and the classification of matter — the periodic table and organic functional groups) and Reactivity (what drives reactions through energetics; how much, how fast and how far through stoichiometry, kinetics and equilibrium; and the mechanisms of proton transfer, electron transfer and electron sharing). Every topic links the chemistry to the data booklet and the experimental and data skills examiners reward.

These notes are organised theme-by-theme according to the official IB syllabus, so you can revise systematically for Paper 1 (Paper 1A multiple choice plus Paper 1B data-based questions) and Paper 2 (short-answer and extended-response). SL students sit no Paper 3 and no options, and the data booklet is provided in every paper, so the focus stays on mastering the core themes and using the booklet quickly.
