Learning objectives
The student will learn to use basic chemical devices to perform chemical-physical analyzes (weight scale, burette, spectrophotometer, pH meter) in order to apply the theoretical concepts learned in the lessons of Medical Chemistry.
Expected learning outcomes
In line with the objectives of the course, the student after learning the safety rules of a chemical laboratory, will operate safely in the laboratory and will use the main analytical instruments (analytical balance, burette, magnetic stirrer, heating plate, pH meter and spectrophotometer UV).
At the end of course the student will be able to carry out analytical determinations by acidimetric titration with indicators and with the use of pH meter and will also be able to construct a working curve for the quantitative determination of the protein content of an unknown solution, using a UV-VIS spectrometer.
