Chemistry Laboratory VIII (Practical)
|
CO84: Calibrate and operate instruments to perform the experiments based on conductance and potential measurement. CO85: Acquire hands-on expertise in performing experiments for analyzing kinetics of a chemical reaction. CO86: Perform scientific experiments as well as accurately record experimental data and analyze the results of such experiments. CO87: Compile and report the results efficiently, and develop communications skills. CO88: Contribute effectively in course-specific interaction. |
Approach in teaching: Power point presentation, laboratory instructions and demonstrations.
Learning activities for the students: Peer learning, hands-on-learning, interpretation of data, record writing and learning through virtual labs.

Scheme of Examination
The duration of the examination will be 5 hrs.
The following exercises will be set in the examinations
Major experiment 35 marks
Minor experiment 20 marks
Viva 15 marks
Total 70 marks
Major Experiment
The exercise carries 35 marks. One major experiment by lot will be given to perform. 5 marks shall be awarded for preparatory work, setting up of an apparatus, neat and methodical work.
30 marks will be awarded for correct observation, use of correct formula, calculation and result within permissible limits as follows:
Theory and procedure 8 marks
Correct observation and proper recording 10 marks
Use of correct formula and calculation 10 marks
Result 2 marks
Minor Experiment
The exercise carries 20 marks. One minor experiment by lot will be given to perform. 4 marks shall be awarded for preparatory work, setting up of an apparatus, neat and methodical work.
16 marks will be awarded for correct observation, use of correct formula, calculation and result within permissible limits as follows:
Theory and procedure 4 marks
Correct observation and proper recording 5 marks
Use of correct formula and calculation 5 marks
Result 2 marks
The permissible limit will be decided by the examiner as it varies with the nature of the experiment.
Viva
Oral questions shall generally be asked over the work assigned to the candidate. The purpose is to find out as to what extent the candidate has understood the basic principles.
