In this era of scientific advancement, Chemistry becomes unavoidable. This book is intended for use in secondary especially advanced level. It will enable both the teachers and the students to focus intensively on each practical. It contains detailed scientific approaches, experiments, explanations and illustrations. Revision questions and Answers are provided topic by topic meanwhile UNEB sample questions are also provided. These questions are intended to form the basics of interactions between teachers and students or student discussion groups. To emphasize this, the simplified language and approach used in this book aims at making chemistry as a subject easy to understand, straight forward, attractive & friendly to students. This book has been developed in line with the most recent developments of Uganda national curriculum center teaching syllabus and UNEB syllabus. It is therefore of great advantage to all secondary schools most especially those which may not be able to provide a wide range of text books for use by their teachers, students & the discussion groups. The trial questions are intended to enhance group discussion for students, reference questions are for exams & seminars. We hope that the student who follows the layout of this book will in the end have got enough experience in enabling a wide range of questions in exams. The students will be fully prepared to both mock and UNEB examinations. We have a vision as most students will turn as scientists to meet the ever increased demand for science graduate in various technical discipline of medicine, agriculture & forestry. And finally, I dedicate this book to my special wife Ms Baseke Bridget (Tutor) Felix Rubangakene Geofrey.
