Using Brønsted–Lowry Theory
Inquiry question: What is the role of water in solutions of acids and bases?
Students:
● 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 (ACSCH102)
● conduct an investigation to demonstrate the use of pH to indicate the differences between the strength of acids and bases (ACSCH102)
● 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 hydrogen sulfate
● construct models and/or animations to communicate the differences between strong, weak, concentrated and dilute acids and bases (ACSCH099)
● calculate the pH of the resultant solution when solutions of acids and/or bases are diluted or mixed
