CBSE Class 12 Chemistry Practical Syllabus 2018

Download latest cbse Class 12 Chemistry Practical syllabus for the session 2017-18. Class 12 Chemistry Board exam will consist of 70 marks and 30 marks will be of practical. There will be complete syllabus in your final/annual exam. Each year cbse keep on issuing revised syllabus. Although the topics and textbooks remain same, the contents within vary year by year. The package also enlists the learning objectives. It is recommended to download new Class 12 Chemistry Practical syllabus 2017-18 and be on safe side.

We’ve got several queries from students throughout the country regarding their poor performance in the board exams. One noteworthy point was that most of them didn’t bother about the syllabus issued by CBSE, they just practised the sample papers or directly appeared in board exams. It’s very important to avoid such situation and practise at least sample papers issued by cbse and previous year questions. These syllabi are also very helpful for JEE Mains, JEE Advanced, NEET etc.exams. Syllabus acts as prima facie for your CBSE exam. It reduces the topics, tells the weightage of each chapter so that you can invest more time on important topics.

Here we have presented the CBSE syllabus for Chemistry Practical class 12 in the same format as released by CBSE, without any changes or editing from our side. Students are advised to download the class 12 cbse Chemistry Practical syllabus for the March 2018 exam even if you have the previous year syllabus because there might be changes in the syllabus, question pattern and weightage of each topic.

PROJECT

Scientific investigations involving laboratory testing and collecting information from other sources.
A few suggested Projects.
 Study of the presence of oxalate ions in guava fruit at different stages of ripening.
 Study of quantity of casein present in different samples of milk.
 Preparation of soybean milk and its comparison with the natural milk with respect to curd formation,
   effect of temperature, etc.
 Study of the effect of Potassium Bisulphate as food preservative under various conditions (temperature, concentration, time, etc.)
 Study of digestion of starch by salivary amylase and effect of pH and temperature on it.
 Comparative study of the rate of fermentation of following materials: wheat flour, gram flour, potato
    juice, carrot juice, etc.
 Extraction of essential oils present in Saunf (aniseed), Ajwain (carum), Illaichi (cardamom).
 Study of common food adulterants in fat, oil, butter, sugar, turmeric power, chilli powder and pepper.

Note: Any other investigatory project, which involves about 10 periods of work, can be chosen with the
approval of the teacher.
