... in a neutral water solution each ion would have a concentration of 1 x 10-7 mole/liter. Whether a solution is acidic or basic depends upon the relative concentrations of the two ions. In an acid solution, the hydrogen-ion concentration is greater than 1 x 10-7 mole/liter. 1, record 1, English, - hydrogen%2Dion%20concentration

Si les concentrations sont exprimées en moles par litre, à 25 °C, le produit (H+) (OH-) est égal à 1x10-14. [...] Cette constatation amena [...] Sorensen à proposer, en 1909, l'utilisation d'une échelle logarithmique dite de «pH» pour la concentration des ions d'hydrogène dans l'eau. [...] Les valeurs du pH de 0 à 14 recouvrent alors l'intervalle des solutions fortement acides aux solutions fortement basiques. 1, record 1, French, - concentration%20des%20ions%20d%27hydrog%C3%A8ne
