GCSE Chemistry: Chemical Changes — Deep Revision Workbook

GCSE Chemistry: Chemical Changes — Deep Revision Workbook is the extended-practice set of a Chemical Changes activity pack, mapped to AQA GCSE Chemistry Topic 4 (spec reference 5.4). Learners work through the reactivity series and displacement, oxidation and reduction in terms of oxygen and of electrons (OIL RIG) for higher tier, reactions of metals with acids and with water, extraction of metals by reduction with carbon, acids, alkalis and the pH scale, strong versus weak acids, neutralisation to make soluble salts, and the electrolysis of molten and aqueous compounds including half-equations and the extraction of aluminium from aluminium oxide in cryolite. Sections 1–4 hold more than thirty auto-marked questions that build from foundation to higher tier; Section 5 is an extended exam-style 6-mark challenge with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
