Manufactured Products

Monitoring and Management‎ > ‎

Manufactured products, including food, drugs and household chemicals, are analysed to determine or ensure their chemical composition

Students learn to:

• deduce the ions present in a sample from the results of tests
• describe the use of atomic absorption spectroscopy (AAS) in detecting concentrations of metal ions in solutions and assess its impact on scientific understanding of the effects of trace elements

• Students:
  perform first-hand investigations to carry out a range of tests, including flame tests, to identify the following ions:
  • phosphate
  • sulfate
  • carbonate
  • chloride
  • barium
  • calcium
  • lead
  • copper
  • iron
• gather, process and present information to describe and explain evidence for the need to monitor levels of one of the above ions in substances used in society
• identify data, plan, select equipment and perform first-hand investigations to measure the sulfate content of lawn fertiliser and explain the chemistry involved
• analyse information to evaluate the reliability of the results of the above investigation and to propose solutions to problems encountered in the procedure
• gather, process and present information to interpret secondary data from AAS measurements and evaluate the effectiveness of this in pollution control
