The self-instruction manual is based on a technique that the author has been successfully using for more than 20 years. With its help, many schoolchildren were able to enroll in chemistry faculties and medical universities. This book is a self-instruction manual, not a Textbook. You will not encounter here a simple description of scientific facts and properties of substances. The material is structured in such a way that, when faced with complex questions that cause difficulties, you will immediately find an explanation from the author. At the end of each chapter there are test tasks and exercises to consolidate the material. For an inquisitive reader who simply wants to broaden his horizons, the Self-Teacher will give the opportunity to master this subject “from scratch.” After reading it, you cannot help but fall in love with this most interesting science - chemistry!
