INSTITUTE OF AERONAUTICAL ENGINEERING
(Autonomous)
B.Tech I Semester End Examinations (Supplementary) January/February, 2018
Regulation: IARE R16
ENGINEERING CHEMISTRY
(Common for all branches)
Time: 3 Hours Max Marks: 70
Answer ONE Question from each Unit
All Questions Carry Equal Marks
All parts of the question must be answered in one place only
UNIT I
1. Define the terms specific, equivalent and molar conductance and explain effect of dilution on
them.
Discuss the construction of Zn battery with relevant reactions occurring during discharge.
2. What is single electrode potential? Derive Nernst equation for single electrode potential.
Describe the construction and working of lead-acid battery with the reactions occurring during
discharge.
UNIT II
3. What is oxidation corrosion and how it takes place? Describe the mechanism of oxidation corrosion.
Explain the process of Galvanization with a neat diagram and mention its applications.
4. What is paint? Explain the constituents and function of paint.
Name and explain the corrosion control method if Mg block are used to protect the corrosion of
underground pipeline.
UNIT III
5. What is EDTA? Explain the determination of total hardness using EDTA method
100 ml of hard water sample required 22.5 ml of M/100 EDTA solution at the end point using EBT
as indicator. The same volume of water after boiling and filtering, the filtered water required 14.5
ml of the same EDTA at the end point with the same indicator. Calculate the total, permanent,
and temporary hardness of water.
6. Discuss the principle and the process involved in the purification of water by reverse osmosis
method.
What is the difference between hard water and soft water? Mention the salts responsible for
permanent and temporary hardness.
