I never managed to get a proper answer for this dotpoint.The question is: Describe the role of a chemist in an industry or enterprise, and a chemical principle used by the chemist. (3 marks) It's from the 2007 HSC paper. |

Analytical Chemist, the determination of what substances are present in samples (qualitative analysis) and how much of each is present (quantitative analysis). You can choose like between 4 or so i think, this one is the easiest to remember.

Off to my notes! An industrial chemist working at a coal testing lab uses a number of instruments and principles in their daily work. Their role may include testing coal for trace elements, for CO2 emmissions and the quality of the coal -- that is, how much energy can be produced by burning a set amount of the coal. A chemical principle they use includes absorption or emission: That is, when an element is atomised it absorbs or emits a certain wavelength of light. This is used in Atomic Absorption Spectophotometry to determine both quantitatively and qualitatively the trace metals found in coal.
