Learning Objectives

Provide a solid background in chemical principles that are particularly important for Analytical Chemistry. Provide the basic knowledge of the solution equilibria, volumetric and gravimetric analysis, and use of common instrumental methods in analytical chemistry. The course is also aimed to develope the right analytical sensitivity required for the chemical laboratory.

Course Structure

The course will be carried out through a first part of lectures to provide the student with the basic background for entering the laboratory, and a part of the laboratory that includes participated lessons, simulations and quantitative analysis with single and group work typology.
