CY2161 ENGINEERING CHEMISTRY 2 SYLLABUS | ANNA UNIVERSITY SECOND SEMESTER SYLLABUS

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)
ti trations,

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 (leadsilver
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.
