Chemistry questions in the GAT are mostly recall-based and at the NCERT level — physical and chemical changes, acids/bases/salts, oxidation–reduction, carbon and atomic structure recur most.

Each topic gives the concept, key points, a worked example and two practice MCQs.

Topics covered in this guide:

1. Physical and Chemical Changes · 2. Elements, Compounds and Mixtures · 3. Properties of Air and Water · 4. Chemical Equations and Laws of Chemical Combination · 5. Acids, Bases and Salts · 6.
