CHARACTERISTICS OF WATER
Carbonate (Temporary) Hardness CaCO3
Non Carbonate (Permanent) Hardness CaSO4
Concentration of Hydrogen-ion, which are expressed in pH units. It is the—Log10H+
Specific Electrical Conductance
- Increases with temperature: values must therefore be related to the same temperature (2%)
Alkanity: Ability to neutralize acid; due to the presence of OH-, HCO3-, CO32-,
Acidity: Water with pH 4.5 is said to have acidity; caused by the presence of free mineral acids and carbonic acids
Turbidity: Measure of transparency of water column; indirect method of measuring ability of suspended and colloidal materials to minimize penetration of light through water.
Dissolved gasses: O2, N2, CO2, H2S, CH4, NH3, etc.
