The educational objective of the course is to provide students the basic principles in analytical chemistry, especially concerning ionic equilibria in aqueous solution. Aim of the course is the introduction of the statistic/chemometric techniques necessary for processing the experimental data acquired in a laboratory of analytical chemistry. Moreover, the course will also provide students the practical information for operating in a chemical laboratory.
Expected learning outcomes
At the end of the course the students will be able to calculate concentrations in solution from equilibrium constants by a systematic approach. The student will be also able to use the basic statistical/chemometric techniques required for extracting/ elaborating / optimising the information collected by experimental measurements. Moreover, the student will have acquired the knowledge to work in a chemical laboratory.
