CBSE Chemistry Practicals Class 11

CBSE Chemistry Practical Class 11 is an important part of the assessment for students. The marks obtained in CBSE Chemistry Class 11 Practical exams are added to the theory marks to prepare the final score of the students in the subject. Therefore, it’s crucial for students to go through the practical syllabus and activities mentioned 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 CBSE practicals and details on project works that they can perform and learn during the academic year.

CBSE Class 11 Chemistry Practical carries 30 marks in the exam. Therefore, students must perform Class 11 Chemistry Practicals effectively to score high marks in the subject. The Chemistry Practical for Class 11 consists of volumetric analysis for 8 marks, salt analysis for 8 marks, content-based experiments for 6 marks,  project work, class record and viva for 4 marks, respectively. All these details are mentioned in the Chemistry Lab Manual Class 11. To download the CBSE Syllabus for Class 11 Chemistry Practicals, click on the link below.
