Alkalinity
The measure of the amount of alkaline buffers-primarily carbonates and bicarbonates-in water. These alkaline substances buffer the water from sudden changes in pH. Total alkalinity is considered key to water balance.
Alkalinity
The capacity of bases to neutralize acids. An example is lime added to lakes to decrease acidity.

alkalinity (AL-ka-LIN-it-tee). The capacity of water to neutralize acids. This capacity is caused by the water's content of carbonate, bicarbonate, hydroxide and occasionally borate, silicate, and phosphate.
alkalinity
the capacity of water to neutralize acids, a property imparted by the water's content of carbonate, bicarbonate, hydroxide, and on occasion borate, silicate, and phosphate.
alkalinity; soil
The degree or intensity of alkalinity of a soil expressed by a value greater than 7.0 on the pH scale See also - alkaline soil - alkalization - saline-alkali soil - sodic soil - soil reaction

Alkalinity: The measurement of constituents in a water supply which determine alkaline conditions. The alkalinity of water is a measure of its capacity to neutralize acids. See pH.
Alkalinity
Alkalinity means the buffering capacity of water; the capacity of the water to neutralize itself. It prevents the water pH levels from becoming too basic or acid. It also adds carbon to water.
A alkalinity
Definition (english only)
A measure of the capacity of water to neutralise acids.
carbonate alkalinity That part of the total alkalinity due to the carbonate ion (CO3 -).
Methyl Orange Alkalinity: A measure of the total alkalinity in a water sample in which the color of methyl orange reflects the change in level.
Phenolphthalein Alkalinity- The alkalinity in a water sample measured by the amount of standard acid needed to lower the pH to a level of 8.3 as indicated by the change of color of the phenolphthalein from pink to clear.
SBV Sauerbindungsvermogen (German); the water's buffering capacity, titratable base, alkalinity, acid-combining strength, usually expressed as mEq/ liter
scavenger animal that eats dead organic matter.
alkalinity A pressure- and temperature-independent property of seawater that determines in part the carbon content of seawater.
pH A scale of acidity (1 - 7) or alkalinity (7 - 14) derived from the logarithm of the concentration of hydrogen ions (10 - 1 - 10 - 14). Phagocyte White blood-corpuscle capable of destroying harmful bacteria.
pH (abbr. power of hydrogen [2]) is a measure of the activity of hydrogen ions (H+) in a solution and, therefore, its acidity or alkalinity. In aqueous systems, the hydrogen ion activity is dictated by the dissociation constant of water (Kw = 1.
pH: An expression of both acidity and alkalinity on a scale of zero to 14, with seven representing neutrality; numbers less than seven indicate increasing acidity and numbers greater than seven indicate increasing alkalinity.
pH
The measure of acidity or alkalinity of a chemical solution, from 014. Anything neutral, for example, has a pH of 7. Acids have a pH less than 7, bases (alkaline) greater than 7.
pH: A measure of acidity or alkalinity on a scale of 0 to 14 where 7 is neutral. A pH less than 7 is acid and a pH greater than 7 is alkaline or base.
Phosphates: Alkaline builders used in detergents to soften water.
It is the quantitative expression of the acidity and alkalinity of a solution and has a scale that generally ranges from about 0 to 14. pH 7 is neutral; <7 is acidic; and >7 is alkaline. [Journal of Physical Chemistry B; v102; 1002-4; 1998.
pH
a logarithmic scale (0-14) that reflects acidity or alkalinity; pH 7 indicates neutrality; acidic solutions have lower pH values; alkaline solutions have higher values ...
Likewise, as the pH number increases by one unit, the alkalinity (basic property) increases by a factor of 10, etc.; tap water may lie in a region from above 6 to below 8.
neutralization : Decreasing the acidity or alkalinity of a substance by adding alkaline or acidic materials, respectively.
Buffer: A substance (or mixture of substances) capable of neutralizing both acids and bases when added to a solution, but without significantly changing its original acidity or alkalinity.
metric tons. In the SWIM area, acid rain is of specific concern because of two primary reasons: 1) wind and weather directions from heavily industrial Midwest states and states with high vehicle emission levels and 2) lack of natural alkalinity soils ...
