Module 8 | Applying chemical ideas

Content 1: Analysis of inorganic substances

Lesson 1 | Testing for ions

  • analyse the need for monitoring the environment

  • conduct qualitative investigations – using flame tests, precipitation and complexation reactions as appropriate – to test for the presence in aqueous solution of the following ions:
    – cations: barium (Ba2+), calcium (Ca2+), magnesium (Mg2+), lead(II) (Pb2+), silver ion (Ag+), copper(II) (Cu2+), iron(II) (Fe2+), iron(III) (Fe3+)
    – anions: chloride (Cl), bromide (Br), iodide (I), hydroxide (OH), acetate (CH3COO), carbonate (CO32–), sulfate (SO42–), phosphate (PO43–)

Lesson 2 | Gravimetric analysis and precipitation titrations

  • conduct investigations and/or process data involving:
    – gravimetric analysis
    – precipitation titrations

Lesson 3 | Analytical techniques

  • conduct investigations and/or process data to determine the concentration of coloured species and/or metal ions in aqueous solution, including but not limited to, the use of:
    – colourimetry
    – ultraviolet-visible spectrophotometry
    – atomic absorption spectroscopy
