basicity, also alkality (English: alkalinity), the strength of a cousin designates. It applies: The more highly basicity, the more highly is also the strength of the cousin. As basic environments with pH values over 7 are considered.
The basicity of a cousin is the larger, the more strongly their ability to take up in or several protons< (>math< H^+> /math - ions) is pronounced. A yardstick for this supplies the pKB value.
The determination of the alkality takes place via titration with an acid (hydrochloric acid) up to a certain pH value (4,3). The result is expressed (univalent) the acid quantity per volume around unit, necessary for the reaching of this pH value, as Säureäquivalent/l (mol of /l).
