- 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: - 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
