This laboratory manual of physical chemistry has been written to the use of B. Sc. Students of various Universities. The main features of the book lies in that it serves as a text on the experiment of physical Chemistry and provides both theoretical and experimental approaches to the subject in a simple manner. I hope that the book will continue to serve the needs of the students community. Those studying for their Bachelor's degree in Physical Chemistry . As the accuracy of the results largely depends upon the accuracy of weights, volumetric glassware and the solution used. The author has tried her best to give representative experiments on almost all aspects of common branches of the subject within the available space. A large number of tables of physical constants have also been given in the end of the book. I wish to express my sincere thanks to Dr. O. P. Pandey and my colleagues of the subject for the valuable suggestions, whose book have been freely consulted for the compilation of the work.
