QCE ChemistryPractice Examination 3

This paper covers

• Unit 3: chemical equilibrium (Kc, Le Chatelier) applied to chlorine/HOCl systems
• Unit 3: Bronsted-Lowry acid-base theory, pH/pOH, Ka/Kb, buffer solutions (HOCl/OCl- pool buffering)
• Unit 3: volumetric analysis - acid-base titration of pool dosing acids/bases with full stoichiometry
• Unit 3: oxidation states, half-equations, disproportionation of chlorine, galvanic/electrolytic cells, electrode potentials, brine electrolysis
• Unit 4: structure, naming, isomerism and IMF analysis of the 12 hydrocarbon-derivative classes
• Unit 4: six core organic reactions, Markovnikov's rule, esterification, multi-step synthesis
• Unit 4: macromolecules (addition/condensation polymers, proteins) and green chemistry
• Unit 4: industrial synthesis (Haber, contact process, biodiesel/bioethanol) with limiting-reagent and percentage-yield stoichiometry
• AO1-AO4 cognition coverage: describe/explain, apply/calculate/deduce, analyse/compare, interpret/evaluate/justify against QCAA cognitive-verb definitions
