#C5.2.1
describe the purpose of representative sampling in qualitative analysis
#C5.2.2
interpret flame tests to identify metal ions, including the ions of lithium, sodium, potassium, calcium and copper
#C5.2.3
describe the technique of using flame tests to identify metal ions
PAG5
#C5.2.4
describe tests to identify aqueous cations and aqueous anions and identify species from test results including:
PAG5
a) tests and expected results for metal ions in solution by precipitation reactions using dilute sodium hydroxide (calcium, copper, iron(II), iron(III), zinc)
b) tests and expected results for carbonate ions (using dilute acid), chloride, bromide and iodide ions (using acidified dilute silver nitrate) and sulfate ions (using acidified dilute barium chloride or acidified barium nitrate)
#C5.2.5
interpret an instrumental result for emission spectroscopy given appropriate data in chart or tabular form, when accompanied by a reference set in the same form
#C5.2.6
describe the advantages of instrumental methods of analysis (sensitivity, accuracy and speed)
#C5.2.7
interpret charts, particularly in spectroscopy
