PH pour Potentiel Hydrogène
Volume équivalent: lors d'un titrage c'est le volume du titrant a apporté Véq tel que
Ca Véq = CbVb, b étant la substance à mesurer
A l'équivalence la courbe de titrage (PH en fonction du volume de titrant apporté) présente un point d'inflexion.
Ampholyte: qui présente à la fois un caractère basique et acide, comme l'eau
Zwittérion: molécule qui porte une charge + et une charge - (de même valeur absolue) sur des atomes non adjacents, comme les acides aminés.
