Total boron
Encyclopedia
The total boron is the sum
of boron
species in a solution
. In the environment these species usually include boric acid
and borate
, for example:
BT = [H2BO3−] + [H3BO3]
where,
BT is the total boron concentration
[H2BO3−] is the dihydrogen borate concentration
[H3BO3] is the boric acid concentration
Total boron is an important quantity when determining alkalinity
due to borate's contribution to a solution's acid
neutraling capacity. Total boron is a conservative element in seawater, and can thus be calculated by simply knowing the salinity.

of boron
Boron
Boron is the chemical element with atomic number 5 and the chemical symbol B. Boron is a metalloid. Because boron is not produced by stellar nucleosynthesis, it is a low-abundance element in both the solar system and the Earth's crust. However, boron is concentrated on Earth by the...
species in a solution
Solution
In chemistry, a solution is a homogeneous mixture composed of only one phase. In such a mixture, a solute is dissolved in another substance, known as a solvent. The solvent does the dissolving.- Types of solutions :...
. In the environment these species usually include boric acid
Boric acid
Boric acid, also called hydrogen borate or boracic acid or orthoboric acid or acidum boricum, is a weak acid of boron often used as an antiseptic, insecticide, flame retardant, as a neutron absorber, and as a precursor of other chemical compounds. It exists in the form of colorless crystals or a...
and borate
Borate
Borates are chemical compounds which contain oxoanions of boron in oxidation state +3. The simplest borate ion, BO33−, has a trigonal planar structure. Other borates are made up of trigonal BO3 or tetrahedral BO4 structural units, sharing oxygen atoms...
, for example:
BT = [H2BO3−] + [H3BO3]

BT is the total boron concentration
[H2BO3−] is the dihydrogen borate concentration
[H3BO3] is the boric acid concentration
Total boron is an important quantity when determining alkalinity
Alkalinity
Alkalinity or AT measures the ability of a solution to neutralize acids to the equivalence point of carbonate or bicarbonate. The alkalinity is equal to the stoichiometric sum of the bases in solution...

Acid
An acid is a substance which reacts with a base. Commonly, acids can be identified as tasting sour, reacting with metals such as calcium, and bases like sodium carbonate. Aqueous acids have a pH of less than 7, where an acid of lower pH is typically stronger, and turn blue litmus paper red...
