DEF

Eau ne contenant pas de matières en solution ou en suspension, de sorte que lorsqu'on y introduit un réactif physique ou chimique déterminé, aucune matière étrangère ne s'y révèle.

OBS

L'eau pure est souvent appelée «eau claire» (en anglais : «clear water») parce que, n'étant troublée par rien, elle est transparente. Lorsqu'on désire faire ressortir l'aspect «sain» de l'eau, du fait qu'elle n'est pas mélangée à des substances nuisibles, on parle d'«eau propre».
