The alkalinity and acidity of water are parameters of great importance for studies of aquatic ecosystems. This paper describes the determination of total alkalinity by using acid-base titration with trichloroacetic acid solution as titrant. Total acidity is determined by titration with ammonium hydroxide...
The pH of water is an intensity factor, while the acidity and alkalinity of water are capacity factors. More precisely, acidity and alkalinity are defined as a water's capacity to neutralize strong bases or acids, respectively. The term "acidic" for pH values below 7 does not imply that ...
The degree ofalkalinityor acidity of a water solution is based on the concentration of hydrogen (H+) or hydroxyl (OH−) ions. The term pH is by definition the negative logarithm of the hydrogen ion concentration. The pH scale ranges from 0 to 14, and pure water has a pH of 7. Each...
pH, Acidity, and Alkalinity The termpHrefers to the concentration ofhydrogen ionsin an aqueous solution, where “aqueous solution” means either pure water or water with small (in terms of molar amounts) quantities of substances dissolved in it. Strong solutions of chemicals, such as one-molar...

This process is enhanced if the soil and rocks have been broken up for various reasons like urban development and mining. Limestone contains high levels of calcium carbonate. When used to decrease the acidity at homes, it can run off into surface waters and raise the alkalinity level. ...
Controlled eutrophication could not produce enough autochthonous biomass as substrate for microbial alkalinity production to change the acidity of the water. Chemical pre-neutralization of the acidic water caused the inorganic carbon concentration to increase, but at the same time, hindered algae growth ...
