Chemistry in Focus: Chapter 6 - Using Brønsted-Lowry Theory
Module 6 IQ2 Using Brønsted-Lowry Theory
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
calculate the pH of the resultant solution when solutions of acids and/or bases are diluted or mixed
Worksheet: Calcuating pH + Solutions
PINV - pH of resultant solutions
construct models and/or animations to communicate the differences between strong, weak, concentrated and dilute acids and bases
PHet Animation - Acid Base 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
