[...] au cours de la neutralisation, il se forme d'abord un composé moléculaire entre l'acide et la base (l'un des deux partenaires pouvant être une molécule de solvant). Ce composé résulte en fait de l'établissement d'une liaison hydrogène entre l'atome H de l'acide et l'atome donneur d'électrons de la base; [...].  1, record 40, French, - liaison%20hydrog%C3%A8ne
