ATAR Chemistry QCE Y12 Unit 3 Topic 1 Chemical Equilibrium • How to convert between Ka and Kb and what this actually means as far as chemical equations go • Website: https://www.atarchemistryqce.com/ • Syllabus points: • Dissociation constants • • recognise that the strength of acids is explained by the degree of ionisation at equilibrium in aqueous solution, which can be represented with chemical equations and equilibrium constants (Ka) • • determine the expression for the dissociation constant for weak acids (Ka) and weak bases (Kb) from balanced chemical equations • • analyse experimental data to determine and evaluate the relative strengths of acids and bases • • use appropriate mathematical representation to solve problems, including calculating dissociation constants (Ka and Kb) and the concentration of reactants and products.
