Elementary Electrochemistry

ABOUT THE COURSE: This course would highlight the basic concepts of electrochemistry in the elementary level and will be combined with some basic experiments to understand the theories. Construction of electrochemical cells, fuel cells and their applications, laws of electrolysis, theory of conduction of electricity in solution, ionic equilibrium etc will be discussed in detail. Practical applications like cyclic voltammetry and polarography will be introducedINTENDED AUDIENCE: B.Sc Chemistry Students PREREQUISITES: Knowledge of thermodynamics INDUSTRY SUPPORT: Chemical industry
