*The chemical composition of

water

*A very important indicator of the chemical composition of water is the hydrogen ion concentration? Water reaction – pH. Varies in the range from 6.5 to 8.5. The reason for reducing the pH to approx. 4 are acidic precipitation, the presence of large amounts of humic acids and acidic wastewater pollution. The increase in the concentration of OH ions may be due to contamination with sewage water alkaline and eutrophic waters of the effect of intensive growth of algae consume carbon dioxide. In this case the observed fluctuations in the pH value during the day as a result of varying the intensity of photosynthesis.

*Structure and chemical

properties

*In the liquid phase continuously formed and break hydrogen bonds between water molecules. Water is easy protonation and deprotonation of acids to form a hydronium ion H3O +. Jon is also connected to hydrogen bonds forming a Zundel cation H5O2 +, H9O4 + Eigen cation and larger agglomerates. The crystal structure of the hydrogen bonds are broken and do not determine the crystallographic structure of hexagonal water. When subjected to water pressure of more than 3900 MPa, the water density increases to about 1.5 g / cm³ and ice is formed at a temperature above 0 ° C.

*Water

*Water - the compound of formula H 2 O present at standard conditions in the liquid state. The gaseous water is defined as water vapor in the solid state - ice. Word of water as a chemical name can refer to any state of aggregation.

*Mineral water

*Mineral water is water from a mineral spring that contains various minerals, such as salts and sulfur compounds. Mineral water may be effervescent due to contained gases.

*„Taking the waters"

*Traditionally, mineral waters were used or consumed at their spring sources, often referred to as "taking the waters" or "taking the cure," at developed cities such as spas, baths, or wells. The term spa was used for a place where the water was consumed and bathed in; bath where the water was used primarily for bathing, therapeutics, or recreation; and well where the water was to be consumed.

*Bottled water

*In modern times, it is far more common for mineral water to be bottled at the source for distributed consumption. Travelling to the mineral water site for direct access to the water is now uncommon, and in many cases not possible (because of exclusive commercial ownership rights). There are more than 3,000 brands of mineral water commercially available worldwide.
