Course Synopsis

This course includes theoretical as well as practical learning of basic techniques used in inorganic chemistry for characterization. It starts with simple techniques like conductometry, potentiometry and gravimetry. It then moves to advance techniques like UV/Vis spectroscopy, FTIR, Flame photometry and atomic absorption spectrometry.

Course Learning Outcomes

At the end of this course, students would be able to characterize any unknown sample by using basic to advance techniques. They will be able to handle sophisticated instruments with required skill.
