Course Objectives :
The course aims to make the students aware of the different chromatographic techniques, to make students learn about the synthesis of different metal complexes and to identify them with the help of IR spectra and to make students understand about the different concepts behind the gravimetric and volumetric techniques and its uses in separation of different metal ions from a given mixture.
