Alkalinity
The capacity of bases to neutralize acids. An example is lime added to lakes to decrease acidity.

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.
Alkali
Any substance with a pH higher than 7.
Atmosphere
The layer of gases that surround and protects the Earth. It is about 700km thick.
alkali soil
(1) A soil having a high degree of alkalinity (pH of 8.5 or higher) or having a high exchangeable sodium content (15% or more of the exchange capacity) or both.
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: 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.
Alkaline (synonym basic, caustic)
Having the properties of a base, a pH greater than 7. Usually used as an adjective, i.e. "alkaline soil". See Acid, Base, pH
Alluvial deposit ...
Alkali
Any compound having highly basic properties; i.e., one that readily ionizes in aqueous solution to yield OH anions, with a pH above 7.0, and turns litmus paper blue.
alkaline (Al-ka-LINE). The condition of water or soil which
contains a sufficient amount of alkali substances to raise the
pH above 7.0.
alkali : Various soluble salts, principally of sodium, potassium, magnesium, and calcium, that have the property of combining with acids to form neutral salts and may be used in chemical water treatment processes.
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.
Alkali
Chemicals with high pH are alkaline in nature and are refers as alkalis. They form soluble soaps with fatty acids and are used to neutralize acidic solutions.
Alluvial soils ...
A alkalinity
Definition (english only)
A measure of the capacity of water to neutralise acids.
Alkali a classification of substances that liberate hydroxide ions in water, to form caustic and corrosive solutions which turn litmus paper blue, with a pH higher than 7, for example sodium Hydroxide.
Hard Water- Alkaline water containing dissolved salts that interfere with some industrial processes and prevent soap from sudsing.
Hauler- Garbage collection company that offers complete refuse removal service; many will also collect recyclables.
carbonate alkalinity That part of the total alkalinity due to the carbonate ion (CO3 -).
alkaline phosphatase an enzyme that hydrolizes organic phosphorus compounds, making some P available as soluble inorganic phosphate ...
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.
Mercury - Mercury is a toxic heavy metal released into the atmosphere, most significantly, through the burning of coal in coal-fired power plants and from Hg-cell chloralkali plants where Hg is used as a flowing electrode used to reduce Na+ to ...
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.
Acids and alkalis are the chemicals at each end of the pH spectrum. The scale runs from 0 (acid) to 14 (alkali). At both ends the chemicals are very reactive and corrosive, but in between or mixed together they become neutral.
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.
The area is characterized by an environment of alkaline soils, low rainfall and humidity, high wind movement, intense sunlight and high evapotranspiration rates.
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 ...
Although the oceans will remain alkaline, marine biologists predict that a shift toward greater acidity could threaten the survival of coral reefs and plankton"an essential and fundamental link in the marine food chain.
pH: Measure of acidity. Stands for Òthe negative logarithm of free hydrogen ionsÓ in water. Water of low pH is acidic; high pH is basic, or alkaline.
Point Source: A pipe that discharges effluent into a stream or other body of water.
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.
