Chemical and Physical properties of water

Clean water is a clear liquid with no taste, color and smell. The molecular mass of water is 18.016 a.m.u. The water molecule is non-linear; the angle between the bonds of H-O-H is 104 ° 27 '. Links of H-O is polar and covalent. Electron density is shifted to an oxygen atom. Therefore, oxygen is able to attract a hydrogen atom of neighboring water molecules in order to form hydrogen bonds. Due to the high polarity of water molecules, it becomes a unique solvent other polar compounds.

Thus, each water molecule can form four hydrogen bonds involving two uncoupled electron pairs of the oxygen atom and two hydrogen atoms that are polarized.

There are many anomalous properties of water that exist just due to the peculiarities of the structure of the water molecule. Thus, water has the highest specific heat among liquids. The thermal capacity of water from 0C to 37C degrees is reduced, and it is increasing from 37C or more degrees. It turns out that it is heated more easily and cooled faster at the temperature of 37 ° C degrees.

The density of water varies abnormally because of the heating and cooling. Water is continuously reduced in volume as the temperature is lowered from 100C to 3,98 C, and its density is about 1g / ml. But the opposite phenomenon occurs after crossing the border of 3,98 C. Density decreases sharply because of the crystallization, and ice`s density is 0.91 g / ml. Thus, when a unit volume of water of 3,98 C weighs more than 0C. When it is cooled below four degrees ice forms and it pops up, but underneath it is always some water.

Water has the highest surface tension of any liquid (except for mercury).

Water is a weak electrolyte and dissociates to a very small degree. Therefore, distilled water does not conduct electricity.

The relative dielectric constant of water is 80. This is a very high value, which explains its ability to be a universal solvent.

The natural water itself is a mixture of different chemical compounds, mostly salts. Except for various salts, there are also gases dissolved in water. Modern methods of analysis help to find out that seawater contains the two-thirds of the table of the chemical elements.

The water dissolves the salt to separate ions. Thus the resulting ions can combine with water making more complex groups which are in a state of dissociation.

Water hardness is determined by the presence of water-soluble calcium and magnesium salts. Precipitate on the vessel wall is highlighted. Rainwater is the most soft upon heating of such water. Hard water can be softened by boiling or addition of chemical reagents. Water is one of the causes of corrosion.

Clean water is a clear liquid with no taste, color and smell. The molecular mass of water is 18.016 a.m.u. The water molecule is non-linear; the angle between the bonds of H-O-H is 104 ° 27 '.
