CBSE Chemistry Practicals Class 11

Chemistry Practical Class 11 is an important part of assessment for students. The marks obtained in CBSE Chemistry Class 11 Practical exams are added in the theory marks to prepare the final score of the students in the subject. So, It’s become crucial for students to go through the practicals and activities provided in the Chemistry Lab Manual Class 11. It will help them in scoring high marks in the practical exams. Here, students will find the list of practicals and project works of the Chemistry Lab Manual Class 11 which students have to perform during the academic year.

CBSE Class 11 Chemistry Practical exam consists of 30 marks. Therefore, students must perform Class 11 Chemistry Practicals thoroughly to score high marks. The term 1 Chemistry Practical for Class 11 consist of volumetric analysis for 8 marks, content based experiments for 2 marks , class record and viva for 5 marks. Whereas, CBSE Class 11 Chemistry Term 2 Practical have salt analysis for 8 marks, content based experiments for 2 marks, project work and viva for 5 marks. All these details are provided in the Chemistry Lab Manual Class 11.

CBSE Class 11 Chemistry Practical Experiments

Chemistry is an interesting subject as it gives knowledge about the behaviour of matter, composition, properties, etc. The Class 11 Chemistry practical Exam Syllabus is designed by board in such a way that it evaluates a student’s expertise thoroughly. Students must go through these practicals and Chemistry Lab Manual Class 11 to prepare more efficiently for the exam.

List of Suggested Projects for CBSE Class 11 Chemistry Practical

Scientific investigations involving laboratory testing and collecting information from other sources.

A few suggested Projects

• Checking the bacterial contamination in drinking water by testing sulphide ion.
