The molecule of water has an angular structure: the nucleuses which are included in its structure, form isosceles triangle, in the basis of which there are two protons, and in top - nucleus of atom of oxygen. The atom of oxygen in a molecule of water is in a condition sp3- hybridisation.

PHYSICAL PROPERTIES:

Water is the liquid without colours, smell, taste in thick layers of light-blue colour, as it absorbs a red part of a spectrum, and reflects dark blue. Water has a number of abnormal physical properties in comparison with connections of similar structure. Temperatures, at which water boils and freezes, are accepted for the standard, accordingly, 100⁰C and 0⁰C (at P = 1 atm). Water environment of the Earth, softening temperature differences in an atmosphere, substantially defines a climate on our planet. oaieii?iaiaiinoe water from the further freezing.

RECEPTION:

The cleanest water turns out at combustion of hydrogen in oxygen. However practically both in laboratory, and in industrial conditions clean water is received by a way of passing it through columns with ionnochangeable pitch. These ways are applied to cleaning water of soluble salts.
