Learning outcomes of the course unit
The course, articulated in theoretical lessons and individual practice training is aimed to supply the necessary basic notions for the qualitative and quantitative determination of substances of pharmaceutical interest. In particular, during the practical training the attention will be focused on the qualitative analysis of inorganic salts and on the quantitative determination of either inorganic or organic analytes.
General and Inorganic Chemistry
