Wet chemistry studies chemical reactions that occur in the liquid phase. It is also called bench chemistry because many of the tests performed are done at a lab bench.

Materials[change | edit source]

Wet chemistry uses laboratory glassware, such as beakers and flasks, without quantitative chemical analysis using instrumentation. Many high school and college laboratories teach students basic wet chemistry methods.

History[change | edit source]

Before the age of theoretical and computational chemistry, it was the main form of scientific discovery in the chemical field. So, some people call wet chemistry classic chemistry or classical chemistry. Today's society and quality control requirements need a high volume of wet chemistry. So, many wet chemistry methods have been automated and computerized for faster analysis.

Uses[change | edit source]

Wet chemistry techniques can be used for qualitative chemical measurements, such as changes in color (colorimetry), but often involves more quantitative chemical measurements, using methods such as gravimetry and titrimetry. Some uses for wet chemistry include tests for:

Wet chemistry is also used in environmental chemistry settings and is used for to test:

  • Biochemical Oxygen Demand (BOD)
  • Chemical Oxygen Demand
  • eutrophication
  • coating identification

It can also involve the elemental analysis of samples, e.g., water sources, for items like:
