It is a part of analytical chemistry that is used to determine the amount of elements in samples and is classified into two groups, classical and instrumental.

In the classical method, the desired substance is dissolved in the necessary acids (digestion of the sample) and the resulting solution, after reaching a certain volume and according to the type of required element, is reacted with the corresponding standard reagents and the concentration of each element is determined based on the existing chemical relationships. between the reactant and the reactant is obtained, which is called “titration”. Other classic methods of sample analysis are as follows:

• Qualitative methods
• Chemical tests
• Flame test
• Quantitative methods
• Gravitational analysis
• Volumetric analysis
• Colorimetric

Some applications of wet chemistry include tests for: acidity-alkalinity (Ph), conductivity (specific conductivity), hardness, melting point, solids or soluble solids, salinity, specific gravity, density, turbidity, viscosity, etc.

Chemistry is also used in knowing the chemistry of the environment and determining the current state of the environment.   

Also, chemical water can be used to monitor water sources for things like: nitrogen, ammonia, chloride, chromium, cyanide, dissolved oxygen, fluoride, nitrogen, nitrate, phosphate, phosphorus, silica, sulfate, and sulfide
