Learning outcomes In this course unit it is intended that the student understands the chemical reactions the classical analytical methods are based on, in order to interpret the results obtained in the chemical analyses. At the end of the course unit the student should be able to:
-Understand the behaviour of electrolyte solutions
-Calculate the pH from acid-base equilibrium
-Identify the requirements for the formation of precipitates and calculate solubilities in different media
-Apply complexing agents on the analysis of metals
-Apply redox equations in chemical analysis
