Introduction
The Chem IB data booklet is one of the most important resources in IB Chemistry. For the 2026 first assessment, it provides all the essential formulas, constants, and reference values you’ll need in the exam.
Many IB students make the mistake of only opening the Chem IB data booklet during the final weeks of revision. The best approach is to practice with it throughout the two-year course so you can navigate it confidently under timed exam conditions.
Quick Start Checklist for IB Chemistry Students
When revising with the Chem IB data booklet, make sure you:
- Learn the layout of sections (tables, constants, equations).
- Practice navigating it quickly during revision.
- Understand which formulas apply to SL vs HL content.
- Memorize exceptions not included in the booklet.
Why the Chem IB Data Booklet Is Essential
- Contains periodic table with atomic numbers and relative masses.
- Provides physical constants like R (gas constant) and Avogadro’s number.
- Lists important formulas: Gibbs free energy, equilibrium, kinetics, acid-base, and redox.
- Ensures students can apply knowledge rather than waste time memorizing.
