Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods. [2] Classical qualitative methods use separations such as precipitation, extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity.

Quantitative analysis (chemistry) In analytical chemistry, quantitative analysis is the determination of the absolute or relative abundance (often expressed as a concentration) of one, several or all particular substance (s) present in a sample. [1] It relates to the determination of percentage of constituents in any give sample.
Wet chemistry. Graduated cylinders and beakers filled with chemicals. Wet chemistry is a form of analytical chemistry that uses classical methods such as observation to analyze materials. The term wet chemistry is used as most analytical work is done in the liquid phase. [1] Wet chemistry is also known as bench chemistry, since many tests are ...
