Nobody can imagine a life without water. In other words, there is no life without water. Every living being on this earth should be drinking plenty of water every day to maintain a healthy body. Even though many of us fail to reach our recommended daily target, we sure understand the extremely vital role of water in our daily health and well-being. Recently, Advertisements and promotional materials on alkaline drinking water claim that alkaline water helps neutralize acids and remove toxins from the body. Few people even go to the extent of emphasizing that it slow down the aging process and prevents cancer. However, there is no significant scientific evidence to support any of the claims made by manufacturers and promoters of water alkalizing machines.
Alkaline water has more excess oxygen and alkaline minerals then neutral or acid tap water. It is highly oxygenated water with the oxygen in the stable bias OH- form that is needed by our cells. Each of these ions is bonded with an alkaline mineral in the all important colloidal form. At pH between 8 to 10, ionized alkaline water will have 100's of times more excess oxygen then neutral tap water and no acid elements or toxic substances in it.
Human body functions best within a pH range of 7.35 and 7.45 neither too acid nor too alkaline. Unfortunately, most of the things we eat and drink are very acidic which causes our body to become more acidic an increases our risk of disease. Alkaline gets rid of the acid wastes produced by the body. These wastes come from the different food and beverages that we drink. Alkaline water also helps eliminate other toxins within the body as they have smaller clusters of water molecules. It acts like a filter that throws out the harmful elements in the human body. At the same time, it fortifies the organs by cleansing them.
Pure water is made completely of H2O molecules loosely bound in a network-like structure in which individual molecules are constantly changing associates. Water molecules show a very slight tendency to dissociate ("ionize") into hydrogen ions and hydroxide ions such as:
H2O → H+ + OH–
However, the extent of this reaction is strictly restricted by the fact that the reverse of this reaction is much quicker, so that on the average, only about two out of every billion H2O molecules are dissociated. No electrical device or chemical additive is capable of increasing these ion concentrations in pure water above this very minute level which is so small that for most practical purposes pure water can be considered to be ion-free, as evidenced by the fact that it will not conduct an electric current.
All water and all aqueous solutions have both H+ and OH– ions. If the quantity of H+ surpasses that of the OH–, the water is known to be acidic. If there are more OH– ions than H+, the water is alkaline. Pure water has equal numbers of both ions and is known to be neutral. Generally, chemists indicate the degree of acidity or alkalinity on the pH scale which runs from about 0 to 14. Acidic solutions have pH values of less than 7, alkaline solutions more than 7. Pure water, being neutral, has a pH of exactly 7. Each unit on the pH scale depicts a hundred-fold change in the ratio of the two kinds of ions; for instance, if the pH is 8, there are 100 times as many OH– ions than H+ ions (that is, [H+] = 10–8, [OH–] = 10–6). Whether water is acidic or alkaline, it will always contain equal numbers of positive and negative electric charges. As, alkaline water contains an excess of OH– ions, it must also contain some other kind of positive ion in addition to H+ in order to balance the opposite charges. This extra positive ion is mostly a metal ion such as sodium, calcium or magnesium. Likewise, acidic water must always contain negative ions in addition to OH–; the most common of these is bicarbonate HCO3–. This means that waters whose pH differs from 7 are never "pure" in the chemical aspect.
