Course Objectives:
There are numerous number of materials used in fabricating and manufacturing devices for the comfort of life. The selection, characterization and suitability assessment of natural raw materials essentially requires principles and concepts of Applied Chemistry for technicians. The course aims to
supplement the factual knowledge gained in the lectures by first hand manipulation of processes and
apparatus. This will develop scientific temper and help to apply the basic concepts and principles in
solving engineering problems.
LIST OF PRACTICALS:
Perform any 12 (twelve) Laboratory Practicals
Volumetric and Gravimetric analysis:
1 Preparation of standard solution of oxalic acid or potassium permanganate.
2 To determine strength of given sodium hydroxide solution by titrating against standard oxalic
acid solution using phenolphthalein indicator.
3 Standardization of KMnO4
solution using standard oxalic acid and Determine the percentage of
iron present in given Hematite ore by KMnO4
solution.
4 Iodometric estimation of copper in the copper pyrite ore.
5 Volumetric estimation of total acid number (TAN) of given oil.
6 Volumetric estimation of
a) Total hardness of given water sample using standard EDTA solution.
b) Alkalinity of given water sample using 0.01M sulphuric acid
7 Proximate analysis of coal
a) Gravimetric estimation moisture in given coal sample
b) Gravimetric estimation ash in given coal sample
Instrumental analysis
8. Determine the conductivity of given water sample.
9. Determination of the Iron content in given cement sample using colorimeter.
10. Determination of calorific value of solid or liquid fuel using bomb calorimeter.
11. Determination of viscosity of lubricating oil using Redwood viscometer.
12. Determination of flash and fire point of lubricating oil using Able’s flash point apparatus.
13. To verify the first law of electrolysis of copper sulfate using copper electrode.
14. Construction and measurement of emf of elector chemical cell (Daniel cell).
15. To study the effect of dissimilar metal combination.
Teachers should use the following strategies to achieve the various outcomes of the course.
• Different methods of teaching and media to be used to attain classroom attention.
• Massive open online courses (MOOCs) may be used to teach various topics/sub topics.
• 15-20% of the topics which are relatively simpler of descriptive in nature should be given to
the students for self-learning and assess the development of competency through classroom
presentations.
• Micro-projects may be given to group of students for hand-on experiences
• Encouraging students to visit to sites such as Railway station and research establishment
around the institution.
Learning Outcomes:
At the end of the course student will be able to
• To express quantitative measurements accurately.
• To practice and adapt good measuring techniques.
• To use various apparatus for precise measurements.
• To understand and differentiate different methods of quantitative analysis.
• To know and understand principles of quantitative analysis using instruments.
• To construct different electrochemical cells used in developing batteries.
• To understand and appreciate methods of corrosion abetments.
