The students will be able to-

 

CO76- apply the knowledge of volumetric and gravimetric techniques in separation and estimation of the amount of different metal ions present in the mixture.

CO77- utilize the chromatographic techniques like paper chromatography and Thin Layer Chromatography for the separation and identification of metal ions.

CO78- prepare inorganic complexes and interpret their IR spectra.
