Abstract
Titration is a volumetric technique which involves the use of known volumes of a known substance to quantitatively determine the amount of a specific substance in an unknown given sample. This technique is one of the fundamental analytical techniques in Chemistry and is applied in life sciences, clinical chemistry, water pollution, industrial analyses and pharmaceuticals. In order to make titration analysis meaningful, one has to understand and learn the principles involved. Volumetric techniques in secondary schools in the South Pacific are generally introduced and taught at senior level (Year 11 - 13) who later take up chemistry as one of their core subjects in tertiary education. In many schools, due to the unavailability of proper volumetric glassware and chemicals (expensive) needed to conduct titration experiments, students often rely on the explanation provided by the teachers to understand the fundamental experimental concepts of volumetric techniques. Quite often the information provided by teachers is ambiguous and students learning become limited. They do not have the opportunity to verify the information because of the unavailability of reliable literature. In the age of Information technology, many Open Education Resources (OERs) are available but in many cases students either do not know how to search for these resources or the resources are at an advanced level. Therefore, a good, step by step volumetric book which is simple, easy to follow and contains worked out experiments is needed. The motivation for writing this book was instigated after years of monitoring the lack of titration skills of freshly enrolled first year undergraduate students in chemistry at tertiary institutions around the South Pacific region. The purpose of writing this book was to enhance students’ skills and knowledge in titration analysis. In writing this book, the authors have tried to be as objective as possible and discussed the relevant concepts to their best ability. To make this book interesting to the readers, the authors have employed simple language and the style gradually changes from that suitable for beginners to that suitable for experts. It is anticipated this book will bring more understanding to the reader about the subject. New and technical words have been highlighted and explained as the subject develops. Pictures of the different glassware used in volumetric analysis take advantage of the visual memory while worked examples stimulate better understanding of the calculations involved. These aspects are expected to generate interest in reading this book. This book contains all the relevant information needed in performing a titration experiment. There are ten chapters in this book and each chapter is arranged as such so that it is complete in itself. There are numerous experiments, some complete with working, while others may be suitable for the reader to try. Although this book is written and aimed for secondary school students who study chemistry, this book goes beyond its immediate needs and is suitable for secondary school teachers, those working in industries and for first year tertiary students doing a course in chemistry. This book is hoped to provide invaluable information to the reader.
