Grade 12 Chemistry – Reaction Mechanisms, Titration & Complex Ions

ChemistryApplied & Practical ChemistryAges 17–18

Three Grade 12 chemistry topics in one model, selected with the topic parameter. The reaction mechanisms tab animates the SN2 and SN1 substitution pathways and electrophilic addition to an alkene, alongside an energy diagram showing activation energy and reaction intermediates. The acid–base titration tab adds NaOH from a burette into HCl drop by drop, builds the pH curve, and turns phenolphthalein pink at the equivalence point, while the complex ions tab adds ligands to a metal ion and shows how coordination number, geometry and solution colour change.
