Inorganic Chemistry III

Specific Foundation / Core

The course is also offered to exchange programme students.

After completing this course, students will be able: • To handle with complex problems on composition and identification of complexes. • To Plan and execute the synthesis of complexes manipulating laboratory apparatus and laboratory instruments. • Operate spectrometers and other laboratory instruments and understand the basic principles governing the respective methods. • To present the results of laboratory studies in the form of written work. • To present research articles using audio-visual media.
