water molecule

-
Water consists of molecules formed by two hydrogen atoms and one oxygen atom. Oxygen has a higher electronegativity than hydrogen at 2.1 on the Pauling scale with 3.5. The water molecule has thereby pronounced partial charges, with a negative polarity on the side of the oxygen and a positive on the side of the two hydrogen atoms. The result is a dipole whose dipole moment in the gas phase is 1.84 Debye. When water acts as a ligand in a complex bond, water is a monodentate ligand. Geometrically, the water molecule is angled, with the two hydrogen atoms and the two pairs of electrons directed into the corners of an imaginary tetrahedron. The angle subtended by the two O-H bonds is 104.45 °. It deviates from the ideal tetrahedral angle (~ 109.47 °) due to the increased space requirement of the lone pairs of electrons. The bond length of the O-H bonds is 95.84 pm each. Because water molecules are dipoles, they have pronounced intermolecular attractive forces and can assemble i...

Mineral contents

-
Slightly carbonated mineral water.
Source of ferruginous water.

 According to its mineral content water is classified as:

 Mineralization very weak: Its dry residue (total minerals present) is up to 50 mg / l.

Mineralization weak: They are those that contain less than 500 mg / l.

Strong Mineralization: Contains more than 1500 mg / l dry residue.

Bicarbonate: Contains more than 600 mg / l of bicarbonates.

Sulfated: Contains more than 200 mg / l of sulfates.

Chloride: It has more than 200 mg / l of chloride.

Calcium: Contains more than 150 mg / l of calcium.

Ferruginous: Contains more than 1 mg / l of iron.

Acid: Contains more than 250 mg / l of CO2.

Sodium: It has a content higher than 200 mg / l sodium.

Magnesium: Its content exceeds 50 mg / l of magnesium.

Fluorinated: Contains more than 1 mg / l of fluoride.

Advantages of water

-
Water (H2O) is a chemical compound of the elements oxygen (O) and hydrogen (H). As a liquid, water is transparent, largely colorless, odorless and tasteless. Water is the only chemical compound on earth that occurs in nature as a liquid, as a solid, and as a gas. The term water is used for the liquid state of matter. In the solid state one speaks of ice, in the gaseous state of water vapor. Water is the basis of life on earth. Of course, water rarely occurs in pure form, but usually contains dissolved parts of salts, gases and organic compounds.

Mineral Water In modern times, it is much more common for mineral waters to be bottled in the source and distributed for consumption. Traveling to mineral water sources for direct access to them is now uncommon, and in many cases is not possible (due to exclusive commercial property rights). There are more than 3000 mineral water brands commercially available worldwide. Origin The biggest differences we can find between a natural water and a mineral water are the taste, the smell and its mineral content. These characteristics are provided by the rocks and sands by which, in most cases, they are filtered and give a unique and special touch depending on the area from which it is extracted.
