3. Experiments Related to pH Change

a. Any one of the following experiments:

  • Determination of pH value of a few solutions obtained from the fruit juices, solutions of both known and varied concentrations of acids, bases & salts using the universal indicator or pH paper.

  • Comparing the pH value of the solutions of both strong and weak acid of similar concentration.

  • Study the pH value change in the titration of a strong acid with a strong base using the universal indicator.

b. Study of pH value change by the common-ion effect in the case of both weak acids and weak bases.

4. Chemical Equilibrium

Any of the experiments from the following.

  1. Study on the shift in equilibrium between the thiocyanate ions and ferric ions by increasing or decreasing concentration of any of the ions.

  2. Study on the shift in equilibrium between the chloride ions and [Co(H2O)6]2+ by concentration change in either of the ions.

5. Quantitative Estimation

  • Preparing the standard solution of oxalic acid.

  • Using a chemical balance.

  • Preparation of standard solution of the sodium carbonate.

  • Strength determination of a given solution of sodium hydroxide by titrating it against oxalic acid's standard solution.

  • Strength determination of a solution of hydrochloric acid that is given by titrating it against the standard sodium carbonate solution.

6. Qualitative Analysis

1. Determination of one anion and cation in salt that is given.

  1. Cations

(Note: Here, we have excluded the insoluble salts)

7. Detection of Sulphur, Nitrogen, Chlorine in the Organic Compounds Project

The scientific investigations include laboratory testing, collecting information from various sources. A few suggested projects are:

  • Study of purification of water methods.

  • Checking drinking water bacterial contamination by sulphide ions testing.

  • Testing the presence of iron, hardness, chloride, fluoride, and more related terns depending upon the regional difference in the drinking water and the study of causes of the presences of these ions above the given or permissible limit (if any).

  • Acidity study of various samples of tea leaves.

  • Study of the effect of acids & bases on the tensile strength of fibers.

  • Determination of the evaporation rate of various liquids.

  • Analysis of vegetable & fruit juices for their acidity.

Important Note: Any other investigatory project that involves about 10 periods of work is chosen with the teacher's approval.

FAQs (Frequently Asked Questions)

1. What is the Practical Syllabus of CBSE Chemistry Class 12, 2018?

Ans: There are going to be three questions as follows.

Question 1- Titration

Question 2 - Salt analysis

Question 3- Finding the functional group.

Also, there will be an investigatory project, whereas the external examiner will take the viva.

Students need to complete their journals from time to time and keep it clear. They should mainly focus on salt analysis as it is the tough part to do at the last moment. Also, it is advised to be thoroughly prepared with the equations of investigatory, if any.

2. How to Prepare for the Practical Exam of CBSE Class 11 Chemistry?

The method called 'Class Reversed' or 'Flipped Classroom' is a growing trend in all the subjects, including Science as well. However, its effect on learning the Chemistry subject can be seen in a twofold manner. 

This technique encourages students to study the lesson before going to the classroom. This concept also familiarises the student with the subject and academic content, making the classroom much easier to follow. Students can then consolidate that knowledge, and they can use their valuable class time to raise important questions.
