Full Description
Using the flexibility and power of Excel, this book offers a novel approach to learning the fundamentals of chemical equilibria. The text allows readers to produce and digest large assemblies of numerical data/calculations while still focusing on the chemistry. It has been designed both as a supplement to an undergraduate quantitative analysis course or as a text in a graduate-level advanced analytical chemistry course. Professional chemists will also find this to be an excellent introduction to spreadsheet applications in the lab and a modern overview of analytical chemistry in a self-study format. The authors include problems at the end of each chapter.
