Analysis of Inorganic Substances 

• 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−)
