Chemistry in Focus: Chapter 7 - Quantitative Analysis
Module 6 IQ3 Quantitative Analysis
conduct practical investigations to analyse the concentration of an unknown acid or base by titration
investigate titration curves and conductivity graphs to analyse data to indicate characteristic reaction profiles, for example:
– strong acid/strong base
– strong acid/weak base
– weak acid/strong base
conduct a chemical analysis of a common household substance for its acidity or basicity, for example:
– soft drink
– wine
– juice
– medicine
calculate and apply the dissociation constant (Ka) and pKa (pKa = -log10 (Ka)) to determine the difference between strong and weak acids
conduct a practical investigation to prepare a buffer and demonstrate its properties (ACSCH080)
Practical - Using a Buffer Solution
describe the importance of buffers in natural systems
explore acid/base analysis techniques that are applied:
– in industries
– by Aboriginal and Torres Strait Islander Peoples
– using digital probes and instruments
