In the process we will consider important questions, such as “How do we extract useful results from experimental data?”, “How do we ensure our results are accurate?”, “How do we obtain a representative sample?”, and “How do we select an appropriate analytical technique?” Before we consider these and other questions, we first must review some basic tools of importance to analytical chemists. With- out this understanding of the basic principles of preparative chemistry and chemical reactions, a knowledge of chemistry reduces to pure memory work.
