One of the most common inorganic anion in water and waste water is chloride (CL- ion). The salty taste produced by chloride concentrations in potable water varies depending on the chemical composition of the water. If the cation is sodium, some waters containing 250 CI- mg/I may have a detectable salty taste. When calcium and … Read more
Acidity of Water – How to Measure It
Water is a chemical compound with two hydrogen atoms and one oxygen atom. The chemical formula for water is H2O. Carbonic acid is produced when water is dissolved in carbon dioxide, which raises the acidity of water or the liquid in the subject. The higher the acidity, the more carbon dioxide has been dissolved in … Read more
