The idea of scripting this manual came after we realized that our laboratories don't have a properly structured book that guides them the way to prepare chemistry reagents with a special emphasis to safety caution to be taken whereas getting them ready. This book is so an effort to produce one manual for the aim. The most vital feature of this Manual is that it lists in alphabetical order the ordinarily used chemical reagents with their molecular formula and ways of preparation with calculations. Written in a very easy and lucid language, the scholars, lecturers and lab-staff should notice this book extraordinarily helpful and handy. It should be also useful to the department of chemistry.
