Qualitative analysis .
? Qualitative analysis consists of methods for establishing the
qualitative chemical composition of a substance—that is, the
identification of atoms, ions, and molecules that enter into the
composition of the substance being analyzed.
? The most important characteristics of all methods of qualitative
analysis are specificity and sensitivity. Specificity characterizes
the ability to detect the presence of an unknown element in the
presence of other elements—for example, iron in the presence
of nickel, manganese, chromium, vanadium, or silicon.
Quantitative analysis
? The quantitative amounts of the chemical elements or of certain
compounds in the analyzed substance. Along with specificity and
sensitivity, the most important characteristic of every method
of quantitative analysis is accuracy.
? The accuracy of an analysis is expressed in a percentage of
error, which in most cases must not exceed 1–2 percent.
? Sensitivity in quantitative analysis is expressed in percentages
