Definition

in a sample, one half of the sum of square of the charge number $z_{i}$ (ISO 80000-10: Atomic and nuclear physics) of $i$ -th ion multiplied by its molality $b_{i}$ (molality) over any involved ion:

I = \frac{1}{2} \sum z_{i}^{2} b_{i}

dans un échantillon, moitié de la somme du carré du nombre de charge $z_{i}$ (ISO 80000-10: Atomic and nuclear physics) du $i$ ème ion multiplié par sa molalité $b_{i}$ (molality) pour tout ion impliqué:

I = \frac{1}{2} \sum z_{i}^{2} b_{i}
