Résumé

To persue our foregoing researches, the problem of anomalous water is considered relative either to necessary conditions for the strong O--H--O hydrogen bonds forming or to liquid phenomena in capillaries. Anomalous water does not exist as allotropic modification of water, and its properties cannot be attributed to impurities, simply. With a good probability, the problem of anomalous water invests a more vast problem concerning the anomalies of physic properties of liquids in capillaries and superficial absorption solid-gas phenomena. The problem of anomalous water is a case of strong perturbation operated on water molecules from very reactive superficial centres (either typical of superficial structure of capillaries, relatively also to the modalities with which the material is first treated, or caused by superficial centres of impurities that act alone or in the structural building of the capillary). That permits, very probably, the forming of water molecule associations characterized by strong O--H--O hydrogen-bond. Finally, the case of HBO2I, cubic modification, is examined; only this modification exhibits strong O--H--O hydrogen-bonds and "anomalous" physical chemical properties relatively to the other two known modifications of metaboric acid (orthorombic and monocline).
