 About The Book  

    The Laboratory Manual of Physical Pharmacy–I contains several important experiments expected to be conducted during the first year B.Pharm course. During the first year of B. Pharm., the students are exposed for the first time to the professional aspects such as pharmacopœial specifications of drugs, standardization and calibration of instruments, apart from the evaluation of physical properties in a laboratory.
    This laboratory manual consists of twenty experiments to be conducted during the year. Broadly, the physical and chemical properties included are: density, viscosity, refractive index, optical activity, partition coefficient, critical solution temperature, surface tension, pH, dissociation constant, colligative properties, solubility cosolvency, heat of neutralization, transition temperature etc.
    Special emphasis has been given on the following:
       1. Concepts and principles are applied to pharmacy.
       2. Model calculations for each experiment help the user in processing and analysing the raw data independently.
       3. Illustrations facilitate the students in handling the instruments and organizing ones laboratory work in a cohesive manner.
       4. Question Bank for guiding students to improve performance.
In fact this book will be found useful for ‘self learning’. It will also serve as a ready reference for the industrial pharmacist.
A special attention is given to change the units from CGS system to SI system. Therefore an appendix has been included for the purpose of interconversion.
