Theories are incomplete without experimentation. So in order to enhance the practical skills of students, the CBSE conducts the practical exams for class 11 chemistry along with theoretical exams to test the scientific aptitude of students. CBSE Class 11th, chemistry Lab Manual has been prepared strictly according to CBSE guidelines which follows the NCERT and other state board curriculum. All the experiments in this Lab Manual have been given in a simple, lucid and interactive manner. The theory given with each experiment gives complete knowledge of each term, concept and definition in order to provide a compact knowledge to the students at one place. Viva-Voce questions are given with each experiment to test students' understanding of related experiments. Mr. Kaushalesh Dwivedi, is the author of this complete lab activity book for class 11 chemistry. All the lab based experiments have well-labeled diagrams which clearly demonstrate the details of the apparatus that are used, the correct way of handling Laboratory apparatus and perform the experiments methodically. The basic purpose of this Lab Manual is to provide the students with appropriate guidance so that they can easily understand, carry out, and document the experiments in the Science Laboratory. The Lab Manual comes with practical lessons followed by lab experiments after each chapter, projects and Notebook for jotting down all the essential information, this develops a better understanding about the concept behind each class 11 chemistry theory, there is an experiment which brings authentic and easy to retain conclusions through its observations and which is verified on a real time basis. The aim of this Science Lab Manual is to help class 11 students to prepare and understand the complex chemistry concepts through experimental approach by utilizing pedagogically enhanced content of the Lab Manual and with a compact knowledge base for improving their analytical, experimental skills and learning abilities.
