Wet Chemistry or Wet Chemistry Techniques are used to perform analysis in the liquid stage.  It is also called Bench Chemistry since many of the tests done are performed at a laboratory bench.

 Many high school and college labs teach pupils basic Wet Chemistry Techniques.

History Of Wet Chemistry Techniques

Before the era of computational and theoretical chemistry, it had been the predominant scientific breakthrough in the chemical area. 

Due to the high quantity of Wet Chemistry that has to be carried out in today’s society and quality management conditions, numerous wet chemistry techniques are automatic and automatic for compact evaluation.

The chemistry subject frequently conjures images of chemists mixing compounds to yield compound and colorimetric responses and/or doing careful titrations. 

From the arena of marine chemistry testing, a number of the basic methods continue to be used to execute both quantitative and qualitative sample investigations. 

While contemporary analytical techniques such as UPLC chromatography and ICP spectrophotometry have definitely enhanced the efficacy of chemistry-based diagnoses, classical wet chemistry methods are still helpful analytical techniques. 

Wet chemistry methods are crucial in the first preparation and work-up of trials destined for analysis via contemporary analytical methods.

Regardless of the crucial role wet chemistry methods perform in contemporary testing procedures, a reasonable number of labs suffer from a shortage of adequately experienced chemists available to execute the necessary wet chemistry methods.  For optimum results, classical wet chemistry methods have to be implemented skillfully with an equivalent understanding of the contemporary methodology. 

However, several contemporary labs cannot fulfill this essential requirement and, for example, have diminished their wet chemistry evaluation supplies. 

Normally Used Wet Chemistry Approaches

Frequent Wet Chemistry methods fall into one of two groups:

  • Instrumental
  • Classical 

Classical Wet Chemistry

Classical Wet Chemistry does not trust using analytic instrumentation, while instrumental wet chemistry, as its name implies –does.

Classical Wet Chemistry might be qualitative or quantitative in character. 

Qualitative wet chemistry tests aim to identify a specific substance or assess whether a specific compound or chemical is within a sample. 

Instrumental Wet Chemistry

Instrumental Wet Chemistry includes easy analytical tools such as laboratory scales, pH meters, automatic titrators, and UV/visible spectrophotometers to estimate the specific sample elements. 

Quantitative investigations in Instrumental Wet Chemistry rely upon those tools to evaluate analytic levels by measuring the absorbance or transmittance of an analytic solution at a certain wavelength using a spectrophotometer.

Weighing a precipitate formed in an analytical response or material missing out of a volatilization response, or measuring the amount of titrant needed to achieve a specific pH value or alternative color intensity or turbidity.

Common Wet Chemistry Techniques:

Following are the some commonly used analysis applied in Wet Chemistry Techniques.

  • Chromatography
  • Specific Gravity
  • Density
  • Turbidity
  • Viscosity
  • Concentration
  • Conductivity
  • Hardness
  • PH (acidity, alkalinity)
  • Solids or dissolved solids
  • Salinity
