Preface : Experience of teaching qualitative analysis over a number of years to large numbers of students has provided the nucleus around which this book has been written. The ultimate object was to provide a text book at moderate cost which can be employed by the student continuously throughout his study of the subject.
It' is author opinion that the theoretical basis of qualitative analysis, often neglected or very sparsely dealt with in the smaller texts, merits equally detailed treatment with the purely practical side. Only can this way, can the true spirit of qualitative analysis be acquired. The book accordingly opens with a long chapter entitled "The Theoretical Basis of Qualitative Analysis", in which most of the theoretical principal which find application in the science and discussed.
The writer would be glad to hear from teacher and others of any error which may have escaped his notice : any suggestions whereby the book can be improved will be welcomed
