Uses
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:
- pH (acidity, alkalinity)
- concentration
- conductivity (Specific Conductance)
- cloud point (nonionic surfactants)
- hardness
- solids or dissolved solids
- salinity
- specific gravity
- density
- turbidity
- viscosity
- moisture (Karl Fischer titration)
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:
- Ammonia Nitrogen
- Chloride
- Chromium
- Cyanide
- dissolved Oxygen
- Fluoride
- Nitrogen
- Nitrate
- Phenols
- Phosphate
- Phosphorus
- Silica
- Sulfate, Sulfide
