Refers to the amount of alkali. An alkali is a chemical that can dissolve in water, combine with acids to form salts, and make acids less acidic.

A chemical property of an aqueous system that implies that there are more hydroxyl ions (OH-) in the system, or a potential to produce more hydroxyl ions, than there are hydrogen ions (H+), or potenti [..]

A measure of a material's ability to neutralize acids. Alkalinities are usually determined using titration.

pH above 7.

Having a pH of more than 7. Also referred to as basic.

Alkalinity is a quantitative measurement of the ability of an aqueous solution to neutralize an acid.Alkalinity is denoted by AT and calculated by adding all the stoichiometric amounts of each base in [..]

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. Alkalinity stabilizes water at pH levels around 7. However, when the acidity is high in water the alkalinity decreases, which can cause harmful conditions fo [..]

A measurement of alkaline rated above 7 on the pH scale.

the capacity of water for neutralizing an acid solution.

Measure of the amount of acid neutralizing bases.

chemistry - the acid neutralizing components in water, usually carbonate (CO32-), bicarbonate (HCO3-) and hydroxide (OH-); often reported in mg/L as CaCO3

(n) pH values above 7

A pressure- and temperature-independent property of seawater that determines in part the carbon content of seawater. Carbonate alkalinity is the sum of the concen- tration of bicarbonate plus two times the concentration of the carbonate ions. Total alkalinity is the amount of acid required to bring seawater to a pH at which all dis- solved inorgani [..]

The total alkalinity (Alk) is defined as the excess of bases over acid in sea water. See section 2.3.2.1 (eq. 2.45) and 4.3.1.

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.

Property of water soluble substances (or mixtures) causing the concentration of hydroxyl ions (OH-) in water solutions to be higher than the concentration of hydrogen ions (H+).

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

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

A measure of the capacity of a solution to resist changes to pH when an acid or base is added. Since a solution that contains carbonates is better able to resist a change in pH, alkalinity is expressed as the concentration of calcium carbonate in the solution. In Ontario, lakes and rivers that flow over limestone bedrock are able to resist the effe [..]

The acid neutralizing capacity of a water is known as alkalinity. For surface waters alkalinity has been called "The Protector of the Stream", since the alkalinity of the water rests sudden changes in the pH of the stream associated with the influx of acid deposition, water containing organic acids, groundwater discharges or indus [..]

The combining power of a base measured by the maximum number of equivalents of an acid with which it can react to form a salt.

Refers to the amount of alkali. An alkali is a chemical that can dissolve in water, combine with acids to form salts, and make acids less acidic.

A measure of water’s ability to neutralize acids.

The capacity of water to neutralize acids, a property imparted by the water's content of carbonates, bicarbonates, hydroxides, and occasionally borates, silicates, and phosphates. Alkaline fluids have a pH value over 7. Anaerobic:

The capacity of water or wastewater to neutralize acids. This capacity is caused by the water's content of carbonate, bicarbonate, hydroxide, and occasionally borate, silicate, and phosphate. [..]

The quantitative capacity of water to neutralize an acid. Generally measured in mg/l, as CaCO3. Ambient Temperature

The capacity for neutralizing an acid.

This is a measure of the capacity of water to neutralize an acid - how much acid can be added to water without causing a significant change in pH. Water does not have to be strongly basic (high pH) to have high alkalinity. In the water industry, alkalinity is expressed in mg/l of equivalent calcium carbonate.

See Total Alkalinity.

The capacity of water for neutralizing an acid solution.

<chemistry> Measure of the power of a solution to neutralise hydrogen ions (H+), usually expressed as the equivalent concentration (mg/L) of calcium carbonate (CaCO3). (13 Nov 1997)

The quantitative capacity of aqueous solutions to react with acids.
