AIM

To  impart a sound knowledge on the principles of  chemistry involving  the different application oriented topics required for all engineering branches.

OBJECTIVES

• The student should be conversant with the principles electrochemistry,     electrochemical cells, emf and applications of emf measurements.

• Principles of corrosion control

• Chemistry of Fuels and combustion

• Industrial importance of Phase rule and alloys

• Analytical techniques and their importance.

UNIT I ELECTROCHEMISTRY       9

Electrochemical cells – reversible and irreversible cells – EMF – measurement of emf – Single electrode  potential  –  Nernst  equation  (problem)  –  reference  electrodes  –Standard  Hydrogen electrode  -Calomel electrode  –  Ion  selective electrode  –  glass  electrode  and  measurement  of

+

pH – electrochemical series – significance – potentiometer titrations (redox - Fe²

vs dichromate and

+

precipitation – Ag

titrations,

-

vs CI

titrations) and conduct metric titrations (acid-base  –  HCI vs, NaOH)

UNIT  II           CORROSION AND CORROSION CONTROL       9

Chemical corrosion – Pilling – Bedworth rule – electrochemical corrosion – different types – galvanic corrosion  –  differential  aeration  corrosion  – factors  influencing  corrosion  –  corrosion  control  – sacrificial anode and impressed cathodic current methods – corrosion inhibitors – protective coatings

– paints – constituents and functions – metallic coatings – electroplating (Au) and electroless (Ni)

plating.

UNIT III           FUELS AND COMBUSTION           9

Calorific value – classification – Coal – proximate and ultimate analysis metallurgical coke – manufacture by Otto-Hoffmann method – Petroleum processing and fractions – cracking – catalytic cracking and methods-knocking – octane number and cetane number – synthetic petrol – Fischer Tropsch and Bergius processes – Gaseous fuels- water gas, producer gas, CNG and LPG, Flue gas analysis – Orsat apparatus – theoretical air for combustion.

UNIT IV           PHASE RULE AND ALLOYS          9

Statement and explanation of terms involved – one component system – water system – condensed phase rule – construction of phase diagram by thermal analysis – simple eutectic systems (lead- silver system only) – alloys – importance, ferrous alloys – nichrome and stainless steel – heat treatment of steel, non-ferrous alloys – brass and bronze.

UNIT V            ANALYTICAL TECHNIQUES          9

Beer-Lambert’s law (problem) – UV-visible spectroscopy and IR spectroscopy – principles – instrumentation  (problem)  (block  diagram  only)  –  estimation  of  iron  by  colorimetry  –  flame photometry – principle – instrumentation (block diagram only) – estimation of sodium by flame photometry – atomic absorption spectroscopy – principles – instrumentation (block diagram only) – estimation of nickel by atomic absorption spectroscopy.
