How to Prepare for CBSE Class 12 Chemistry Practical Exams 2026?

The practicals carry significant weightage for the CBSE 12th Chemistry subject. Students must prepare properly for the Chemistry practicals to get a good score in the subject. Some useful tips to prepare for the CBSE 12th practical exam are listed below:

• Go through each experiment’s aim, principle, and procedure carefully.

• Maintain a neat and updated practical record book with diagrams, etc.

• Revise important precautions, observation tables, and inference steps.

• Perform mock titrations and qualitative analyses to boost confidence before exams.

Example of Experiments for CBSE 12th Chemistry (Lab Work)

Aim:

To prepare acetanilide.

Materials Required:

Process:

• Step 1: Take 5 mL of aniline in a 100 mL round-bottom flask and add the acetylating mixture containing 5 mL acetic anhydride and 5 mL glacial acetic acid. Alternatively, you can use 5 mL of acetyl chloride and 5 mL of dry pyridine as the acctylating mixture.

• Step 2: Fit an air condenser on the mouth of the round-bottom flask after adding a few pumice stones and reflux the mixture gently for 10-15 minutes on a sand bath.

• Step 3: Cool the reaction mixture and pour it slowly into 150-200 mL of ice-cold water with stirring.

• Step 4: Filter the solid, wash it with cold water and recrystallise a small amount of sample from hot water containing a few drops of methanol or ethanol.

• Step 5: Report the yield and the melting point of the compound.
