Total boron

Short description: Sum of boron species in a solution

The total boron (BT) is the sum of boron species in a solution. In the environment these species usually include boric acid and borate, for example:

BT = [H
2BO−
3] + [H
3BO

where

* BT is the total boron concentration
* [H
2BO−
3] is the dihydrogen borate concentration
* [H
3BO
3] 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.
