CBSE Class 12 Chemistry Practicals carry 30 marks towards the annual assessment. Students can easily score good marks in practicals with regular practice and an aware mind. Students must learn the identification of different chemicals and to perform the experiments prescribed in the CBSE practical syllabus. We have provided here the CBSE Class 12 Chemistry Practical Syllabus 2022-2023 for students to download in PDF. With this latest syllabus, students would get to know the practical evaluation scheme and the list of experiments for the current academic session. They must check the guidelines and instructions mentioned in the syllabus and prepare for their practical exam accordingly.
