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
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+vs CI- titrations) and conduct metric titrations (acid-base – HCI vs, NaOH) titrations,
UNIT II CORROSION AND CORROSION CONTROL
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
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
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
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.
