| has gloss | (noun) pH values above 7 alkalinity |
| has gloss | eng: Alkalinity or AT is a measure of the ability of a solution to neutralize acids to the equivalence point of carbonate or bicarbonate. Alkalinity is closely related to the acid neutralizing capacity (ANC) of a solution and ANC is often incorrectly used to refer to alkalinity. The alkalinity is equal to the stoichiometric sum of the bases in solution. In the natural environment carbonate alkalinity tends to make up most of the total alkalinity due to the common occurrence and dissolution of carbonate rocks and presence of carbon dioxide in the atmosphere. Other common natural components that can contribute to alkalinity include borate, hydroxide, phosphate, silicate, nitrate, dissolved ammonia, the conjugate bases of some organic acids and sulfide. Solutions produced in a laboratory may contain a virtually limitless number of bases that contribute to alkalinity. Alkalinity is usually given in the unit mEq/L (milliequivalent per liter). Commercially, as in the pool industry, alkalinity might also be given in the unit ppm or parts per million. |

| subclass of | (noun) (from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than 7 is more acidic); pH scale, pH |

| has gloss | cat: Lalcalinitat o AT és una mesura de la capacitat dun solució per a neutralitzar els àcids als punts dequivalència del carbonat o el bicarbonat. Aquesta està molt relacionada amb la capacitat de neutralització àcida (CNA) duna solució, i molt sovint sutilitza aquest terme incorrectament per a referir-shi. La capacitat de neutralització àcida es refereix a la combinació de la solució i els sòlids (ex., materia en suspensió, o sòlids aqüifers), i en alguns casos la contribució dels sòlids pot dominar la CNA (p.ex., amb els minerals carbonats). |

| has gloss | deu: Die Alkalinität definiert das Säurebindungsvermögen von Böden, Gesteinen und natürlichem Wasser. Der Grad der Alkalinität hängt von der Menge der enthaltenen basisch wirkenden Ionen, hauptsächlich dem Gehalt an Carbonaten ab. Daher unterscheidet man auch zwischen Gesamtalkalinität und Carbonatalkalinität. Aus der Alkalinität ergibt sich die Fähigkeit eines Stoffgemisches oder einer Lösung, Oxonium- oder Wasserstoffionen zu binden. Die Alkalinität einer Lösung kann quantitativ durch Titration mit einer Säure in Gegenwart eines Indikators ermittelt werden. Man nennt diese Größe deshalb auch Säurebindungsvermögen. |

| has gloss | fin: Alkaliniteetti (AT) eli veden puskurikyky tai hapon sitomiskyky tarkoittaa veden kykyä happojen neutraloimiseen. Veden alkaliniteetti riippuu enimmäkseen sen karbonaattisysteemistä, mutta myös vedessä olevat muut emäksiset aineet vaikuttavat sen hapon sitomiskykyyn. Vesistöjen happamoituminen voidaan havaita aluksi alkaliniteetin alentumisena, minkä jälkeen se alkaa näkyä veden pH-arvoissa. Alkaliniteetti ilmaistaan yksikkönä mmol/l (millimoolia/litra). |

| has gloss | ita: Con il termine alcalinità si esprime la quantità di sali con proprietà di alcali disciolti nellacqua. Potrebbe molto semplicemente essere definita il contrario di acidità. Nella pratica essa rappresenta la capacità dellacqua a "resistere" a cambiamenti indotti del suo pH. Viene determinata per titolazione utilizzando i due differenti indicatori fenolftaleina ed il metilarancio. L'unità di misura è espressa in termini di ppm (parti per milione). |

| has gloss | por: Alcalinidade representa a capacidade que um sistema aquoso tem para neutralizar ácidos sem perturbar de forma extrema as actividades biológicas que nele decorrem (efeito tampão natural da água). Este parâmetro, normalmente usado para descrever a qualidade da água, é um factor de capacidade e não de intensidade (como o pH), daí que uma solução com pH neutro possa ter alcalinidade considerável. |
