CBSE Class 11 Chemistry Practical Marking Scheme
In chemistry subject practical also plays a vital role. Students understand the theory by performing the experiments in the lab. So, its important that students must also know CBSE Syllabus of Chemistry Practical and list of experiments included in it. Also, the weightage of Chemistry practical is of 30 marks. So, students must try to score well in practicals also. It will help in increasing their overall score. The table below shows the evaluation scheme of practical exams.
|Evaluation Scheme for Examination||Marks|
|Content Based Experiment||06|
|Class record and viva||04|
CBSE Class 11 Chemistry Practical Syllabus
Micro-chemical methods are available for several of the practical experiments. Wherever possible such techniques should be used:
A. Basic Laboratory Techniques
- Cutting glass tube and glass rod
- Bending a glass tube
- Drawing out a glass jet
- Boring a cork
B. Characterization and Purification of Chemical Substances
- Determination of melting point of an organic compound.
- Determination of boiling point of an organic compound.
- Crystallization of impure sample of any one of the following: Alum, Copper Sulphate, Benzoic Acid.
C. Experiments based on pH
- Any one of the following experiments:
- Determination of pH of some solutions obtained from fruit juices, solution of known and varied concentrations of acids, bases and salts using pH paper or universal indicator.
- Comparing the pH of solutions of strong and weak acids of same concentration.
- Study the pH change in the titration of a strong base using universal indicator.
- Study the pH change by common-ion in case of weak acids and weak bases.
D. Chemical Equilibrium
- One of the following experiments:
- Study the shift in equilibrium between ferric ions and thiocyanate ions by increasing/decreasing the concentration of either of the ions.
- Study the shift in equilibrium between [Co(H2O)6]2+and chloride ions by changing the concentration of either of the ions.
E. Quantitative Estimation
