Preface: the title of this book has been clfanged from calculations of quantitative chemical analysis to calculations of analytical chem istry because the subject matter has been expanded to cover the stoichiometry of both qualitative and quantitative analysis.
Quantitative chemical analysis is performed to accurately determine the concentration of elements in the material comprising a given sample. A variety of analysis techniques are used for metals and alloys to determine the alloy composition of raw materials to verify conformance to a specification or to identify the alloy used to make a specific.

Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods. Classical qualitative methods use separations such as precipitation, extraction, and distillation.

The test of vinegar with potassium carbonate is one type of quantitative analysis—the determination of the amount or concentration of a substance in a sample. In the analysis of vinegar, the concentration of the solute (acetic acid) was determined from the amount of reactant that combined with the solute present in a known volume of the solution.
Quantitative analysis of a sample is very important for several reasons. It gives the details about how much reactant should be used to perform a chemical synthesis reaction to get a certain amount of product, hence the waste of chemicals is reduced (atom economy is increased), it can be used to determine the quality of food or any other product by indicating the presence of appropriate.
