Chapter 3 Electrochemistry

Electrochemistry deals with the study of production of electricity from chemical energy produced in a chemical reaction and the use of electrical energy to bring out non spontaneous chemical transformations. Description of electrochemical cells and difference between galvanic and electrolytic cells is also given. Application of Nernst equation for calculating the emf of galvanic cells is also given. Derivation of relation between standard potential of cell, Gibbs energy of cell reaction and its equilibrium constant is also carried out. Definition of resistivity, conductivity and molar conductivity of ionic solutions is also given. Difference between ionic and electronic conductivity is also done alongwith its method of measurement. Justification of variation of conductivity and molar conductivity of solutions with change in their concentration is also given.
