This course is an introduction to electrochemistry through theory and a few experiments to understand fundamental electrochemical processes. The course will cover the laws of electrolysis, Arrhenius theory of
dissociation, transport number, Debye-Huckel theory, ionic mobility, degree of dissociation and dissociation constants, Debye-Huckel Limiting law and conductometric titrations. Special emphasis will be given on various types of electrochemical cells, standard electrode potentials, liquid junction potential, applications of emf measurements, polarization and overvoltage etc.
