Inquiry question: What is an acid and what is a base?
investigate the correct IUPAC nomenclature and properties of common inorganic acids and bases
conduct an investigation to demonstrate the preparation and use of indicators as illustrators of the characteristics and properties of acids and bases and their reversible reactions
predict the products of acid reactions and write balanced equations to represent:
acids and bases
acids and carbonates
acids and metals
investigate applications of neutralisation reactions in everyday life and industrial processes
conduct a practical investigation to measure the enthalpy of neutralisation
explore the changes in definitions and models of an acid and a base over time to explain the limitations of each model, including but not limited to:
Inquiry question: What is the role of water in solutions of acids and bases?
conduct a practical investigation to measure the pH of a range of acids and bases
calculate pH, pOH, hydrogen ion concentration ([H+]) and hydroxide ion concentration ([OH–]) for a range of solutions
conduct an investigation to demonstrate the use of pH to indicate the differences between the strength of acids and bases
write ionic equations to represent the dissociation of acids and bases in water, conjugate acid/base pairs in solution and amphiprotic nature of some salts, for example:
sodium hydrogen carbonate
potassium dihydrogen phosphate
construct models and/or animations to communicate the differences between strong, weak, concentrated and dilute acids and bases
calculate the pH of the resultant solution when solutions of acids and/or bases are diluted or mixed
