This OCR A Level Chemistry Module 2 Study Guide 2026 is designed to help students revise the Foundations in Chemistry module with focused practice questions and correct answers. It covers atomic structure, isotopes, compounds, formulae and equations, amount of substance, moles, acid–base reactions, redox chemistry, bonding and molecular structure, matching the core areas identified by OCR. The resource is suitable for independent revision, classroom preparation, mock-exam practice and final assessment review. Questions are structured to reinforce calculations, chemical concepts and application of knowledge rather than simply memorising facts. Grade A+ preparation is the goal, but no study resource can honestly guarantee a particular exam grade or a 100% pass rate.
