WACE Chemistry Past Papers 2026
Where to find official WACE Chemistry past ATAR exam papers, what each unit tests, and how to turn a marked paper into a targeted revision plan.
SCSA publishes official past WACE Chemistry ATAR exam papers, marking keys and examination reports for free on its website. Chemistry papers test calculation technique alongside recall, so marking your own attempt against SCSA’s marking key is the fastest way to find where working-out, not just final answers, is losing marks. This page explains what each unit covers, then links you into Revizi’s syllabus-mapped practice for the units a past paper shows you’re weak on.

Past Paper: The WACE Chemistry ATAR examination contributes 50% of your combined course score alongside school assessment, covering Unit 3 (Equilibrium, Acids and Bases, and Redox Reactions) and Unit 4 (Organic Chemistry and Chemical Synthesis). SCSA’s marking keys show exactly how partial credit is awarded for working-out — review these line by line, not just the final mark.
Topics Covered
Unit 3: Equilibrium, Acids and Bases, and Redox Reactions
- Chemical equilibrium systems (dynamic equilibrium, Le Chatelier’s principle)
- Acids and bases (pH, pKa, buffers, titrations)
- Oxidation and reduction (half-equations, galvanic and electrolytic cells, standard electrode potentials)
Unit 4: Organic Chemistry and Chemical Synthesis
- Properties and structure of organic materials (functional groups, nomenclature, isomerism)
- Chemical synthesis (reaction pathways, stoichiometry and percentage yield, industrial processes)
