Practical Chemistry
We are very glad to present this book on “Practical Chemistry’’ in the hands of S.Y.B.Sc. students. The book is strictly written according to the semester pattern syllabus framed by the board of studies in Chemistry, KBC NMU Jalgaon, for Second year B.Sc to be implemented from June 2019 and is written in very simple language giving exhaustive details. The book will help students performing experiments in effective way. We hope, this book will be useful for students and teachers.
