2. Analysis for salts in water
• sources of salts found in water (may include minerals, heavy metals, organo- metallic substances) and the use of electrical conductivity to determine the salinity of water samples • the application of mass-mass stoichiometry to gravimetric analysis to determine the mass of a salt in a water sample • the application of colorimetry and/or UV-visible spectroscopy, including the use of a calibration curve, to determine the concentration of coloured species (ions or complexes) in a water sample • the application of atomic absorption spectroscopy (AAS), including the use a calibration curve, to determine the concentration of metals or metal ions in a water sample (excluding details of instrument).
