Chemistry 24 - Some interesting facts (: "Ionized water" is nothing more than sales fiction; the term is meaningless to chemists. Pure water (that is, water containing no dissolved ions) is too unconductive to undergo signficant electrolysis by "water ionizer" devices. *Pure* water can never be alkaline or acidic, nor can it be made so by electrolysis. Alkaline water mustcontain metallic ions of some kind — most commonly, sodium, calcium or magnesium. The idea that one must consume alkaline water to neutralize the effects of acidic foods is ridiculous; we get rid of excess acid by exhaling carbon dioxide. If you do drink alkaline water, its alkalinity is quickly removed by the highly acidic gastric fluid in the stomach. Uptake of water occurs mainly in the intestine, not in the stomach. But when stomach contents enter the intestine, they are neutralized and made alkaline by the pancreatic secretions — so all the water you drink eventually becomes alkaline anyway. The claims about the health benefits of drinking alkaline water are not supported by credible scientific evidence. "Ionized"/alkaline water is falsely claimed to be an anti-oxidant. It is actually an oxidizing agent, as can be seen by its ability to decolorize iodine (see video) There is nothing wrong with drinking slightly acidic waters such as rainwater. "Body pH" is a meaningless concept; different parts of the body (and even of individual cells) can have widely different pH values. The pH of drinking water has zero effect on that of the blood or of the body's cells. If you really want to de-acidify your stomach (at the possible cost of interfering with protein digestion), why spend hundreds of dollars for an electrolysis device when you can take calcium-magnesium pills,Alka-Seltzer or Milk of Magnesia? Electrolysis devices are generally worthless for treating water for health enhancement, removal of common impurities, disinfection, and scale control. Claims that "ionized" waters are antioxidants are untrue; hypochlorites (present in most such waters) are in fact oxidizing agents. abstracted from: http://www.chem1.com/CQ/ionbunk.html Posted on: 2010年7月31日星期六 Posted at: 7/31/2010 10:10:00 下午
