Learning objectives
Providing a basic knowledge of the most important chemical principles in Analytical chemistry, especially concerning ionic equilibria in aqueous solution. Introducing the statistic/chemometric techniques necessary for processing the experimental data acquired in a laboratory of analytical chemistry Providing the practical information for operating in a chemical laboratory at didactic level.
Expected learning outcomes
The student will be able to calculate concentrations in solution from equilibrium constants by a systematic approach. The student will be able to use the basic statistical/chemometric techniques required for extracting/ elaborating / optimising the information collected by experimental measurements. The student will be able to practice the most basic laboratory operations.
