Ha el tudod olvasni a Londoni Southbank University weboldalán azt a pár oldalt, akkor rájössz, hogy ez:
A vizbontás az ábrán látható vastag fehér kötések felbontása. 1db H3O ion meg 1db OH ion febontásához pont annyi energia kell mint 2 db H2O felbontásához
NEM igaz, mert amikor a vízmolekulák összeállnak , akkor a következõ állapot lép fel:
The hydrogen bond in water is part (about 90%) electrostatic and part (about 10%) covalent [96]d and may be approximated by bonds made up of covalent HO-H····OH2, ionic HOδ--Hδ+····Oδ-H2, and long-bonded covalent HO-··H––O+H2 parts with HO-H····OH2 being very much more in evidence than HO-··H––O+H2, where there would be expected to be much extra non-bonded repulsion. Hydrogen bonding effects all the molecular orbitals even including the inner O1s (1a1) orbital which is bound 318 kJ mol-1 (3.3 eV) less strongly in a tetrahedrally hydrogen bonded bulk liquid phase compared to the gas phase [1227]. X-ray spectroscopic probing indicates that the electron transitions between molecular orbitals (changing with the local hydrogen bonding topology) with differing such contributions may shift on a time scale of less than a femtosecond. Contributing to the strength of water's hydrogen bonding are nuclear quantum effects (zero point vibrational energy) which bias the length of the O-H covalent bond longer than its 'equilibrium' position length (as the shorter HO-H····OH2 hydrogen bonds are stronger), so also increasing the average dipole moment [554].
