The first part of the course covers an introduction into measurements in analytical chemistry and a short introduction into statistics. The second part provides an introduction to the basic instrumental methods of chemical analysis which are commonly used in analytical laboratories; these include spectrophotometry and atomic absorption. Next, important titrimetric methods will be covered: acid-base, complexometric, or redox titrations. Titrations still play an important role in the modern analytical laboratory, to a large extent because many titrations can be fully automated. However, the basic reactions and methods of indication are the same. Particularly the study of the chemical equilibrium is fundamental for all titrimetric methods. Towards the end of the course basic separation techniques including chromatography will be covered. Spreadsheets are introduced for calculations in the lectures and further exercises are done in the tutorials. Theory is brought to practice in the laboratory using a wide range of typical examples.
The course forms part of the accredited degree program required for Membership of Royal Australian Chemical Institute Inc. and Chartered Chemist qualifications.
