CBSE Class 11 Chemistry Practical Syllabus

11th Standard may not have boards. But it is still as important to ace the exams like Chemistry Practical in it as the standards 10th and 12th. 11th plays an important role in a student’s life. How? Well, because of the following points below.

• It is in 11th that the students get to learn a few new concepts

• The students  get to learn the subjects which they have chosen

• It builds a foundation for the concepts that will be followed in class 12th

• It is when the students do not have to stress about their boards but still have to focus on their learning

The subjects like Chemistry hold a lot of importance when it comes to the student’s 11th exams. So, it also becomes a must to ace this subject’s exam, whether theoretical or practical. Although it is for sure that one will definitely need to have a good grasp on their CBSE Class 11 Chemistry Practical syllabus and Theory Syllabus.

About the Subject Chemistry

Now, when a student chooses Chemistry to major in their 11th class, it is a given that they will get to do a lot of experiments. And why not? After all, the subject is really about that only. And so there is no denying that they will not only have theoretical exams, but also have practical exams. 

Marking Scheme for Chemistry Exams

It is a given that all the students are given their final scores based on the marks that they have scored in both of their exams. However, one can get used to going through the syllabus or just remembering it, after having practised it all year long. But it is with their practical exam that they may find a few hurdles. And in order to not go through that, they must be very particular in having a good look at their CBSE Class 11 Chemistry Practical Syllabus. 

Class 11 Practical Syllabus - Chemistry

There are various experiments for CBSE Class 11 chemistry students, who are going to attempt their practical exams soon. Students can also find the entire CBSE practical syllabus of Class 11 chemistry, as given below. The manual of Chemistry Lab of Class 11 prepared in accordance with the latest syllabus for Class 11 chemistry prescribed by the board of CBSE. At Vedantu, our experts and teachers have taken the utmost care while preparing for the lab manual of Class 11 chemistry.

Let us look at how to write chemistry practical Class 11 CBSE.

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 terms 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.

Proper Preparation with the CBSE Class 11 Chemistry Practical Syllabus

If you think that preparing for your Chemistry Practical exam would be hard, then that is not really the case. When it comes to having the students get ready for these, they are always asked to revise it all before a few weeks of their exam. Or the students may also practice the experiments with the permission of their teacher in the school laboratory. It is also a better idea to ask the teacher to help you out.
