The purpose of this course is to enable students to appreciate the importance of uniform ionic motion of ions in solution in presence of a potential difference. The course will enable students to apply principles of thermodynamics to solutions of electrolytes where quantities such as activity and activity coefficient will be considered In this course, students will learn thermodynamic properties of reactions that take place in an electrochemical cells, use thermodynamic arguments to derive an expression for the electric potential of such cells and show how the potential can be related to the compositions of the cell. The course will also show how electrochemical techniques can be used to measure the pH of solutions, Pka of weak acids, the solubility of sparingly solute salts, standard Gibbs energy, enthalpy and entropy of reactions. Finally the course will look at the kinetics of electrode reactions in which learners will appreciate the characteristic relation between the current and the over potential at an electrode leading to the development of polarography and cyclic voltammetric methods.
