●      Principles of polymer chemistry and engineering applications of polymers

●      Chemistry of engineering materials

UNIT I           ELECTROCHEMISTRY                                                                        9

Introduction – Kohlrausch’s law, problems; Electrode potential – Nernst equation, problems; Reference electrodes – standard hydrogen electrode, calomel electrode; Ion selective electrode – glass electrode and measurement of pH; Electrochemical series -  significance; Types of cells - galvanic, reversible and irreversible cells; EMF – measurement of emf; Conductometric titrations (acid – base:  HCl vs NaOH); Potentiometric titrations (redox:  Fe²⁺ vs dichromate and precipitation: Ag⁺ vs  Cl^-).

UNIT II          CORROSION AND CORROSION CONTROL                                   9

Corrosion – causes; Mechanisms - Chemical corrosion – Pilling – Bedworth rule – electrochemical corrosion - galvanic corrosion, differential aeration corrosion; Factors influencing corrosion; Corrosion control –  selection of materials & design -  sacrificial anode and impressed cathodic current methods – corrosion inhibitors; Protective coatings – paints – constituents and functions – metallic coatings (electroplating (Au) and electroless plating (Ni)).
