Ionized Alkaline Water???

Pure water (water containing no dissolved ions) is neutral. It can never be can be made alkaline or acidic by means of electrolysis. Pure water is non-conductive and cannot undergo significant electrolysis by “water ionizer” devices.   If water comes from a well and contains dissolved salts or “hardness ions” such as calcium or magnesium in medium concentrations, electrolysis might be possible, but it will not be effective in removing impurities.  It should be noted that groundwater is usually somewhat alkaline to begin with.

Additionally, the pH of drinking water has zero effect on that of the blood or of the body’s cells.

“Ionized water” is meaningless to chemists.  The term, “pH-balanced water” is scientifically meaningless and nothing more than a come-on for nostrums and products of dubious value.

Alkaline water must contain 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. When this is not adequate, the kidneys adjust urinary pH accordingly.
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.

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.

“Ionized”/alkaline water is falsely claimed to be an anti-oxidant. 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.

Claims that “water ionizers are approved for use in Japanese hospitals” are misleading: these “approvals” merely attest to the machines’ safety — that they will not electrocute you! My understanding is that the Japanese Health Ministry is highly critical of therapeutic claims made for alkaline water.

“Ionized water” is one of many products and panaceas that the wonky-water wellness industry flogs onto the large segment of the general public that lacks the scientific background to distinguish scientific fact from pseudoscientific hype when the two are closely intertwined. The purpose of this page is to critically examine some of the claims about “ionized” and alkaline waters from the standpoint of modern chemistry and physiology in order to provide you with the information you need to make your own informed decision before opening your wallets to the hucksters of these products and whose claims are totally lacking in scientific support.

What most of these outfits actually sell are grossly overpriced electrical devices that purport to produce “ionized” and alkaline water by the process of electrolysis. Many of these “water ionizers” appear to have their origins in Japan and Korea, two countries whose populations seem to be particularly susceptible to being taken in by pseudoscientific water-treatment schemes. In North America, distribution of these dubious devices has depended largely on multi-level marketing schemes that enroll science-ignorant dealers to exploit even-more-vulnerable consumers while enabling the manufacturer to maintain a low profile to regulatory agencies such as the FTC.

Many “water ionizer” devices depend on the addition of ordinary salt to make the water more conductive. Electrolysis of a dilute sodium chloride solution liberates hydrogen gas and hydroxide ions at the cathode, producing an alkaline solution that consists essentially of sodium hydroxide NaOH which can be drawn off as “alkaline water”. At the anode, chloride ions are oxidized to elemental chlorine. If some of this chlorine is allowed to combine with some of the hydroxide ions produced at the cathode, it disproportionates into hypochlorous acid HOCl, a weak acid and an oxidizing agent. Some ionizer devices allow the user to draw off this solution for use as a disinfecting agent. In many cases the two streams can be combined to form a mixture consisting of both HOCl and sodium hypochlorite (equivalent to diluted ordinary laundry bleach), depending on the pH desired.

 

The fables

 The facts

“Ionized water” machines actually bring about the electrolysis of ordinary water.If the water is pure enough to be potable, the amount of electrolysis that actually occurs is too small to be significant.
These devices separate the alkaline water (produced at the negative electrode) from the acidic water (produced at the positive electrode), allowing you to draw them off separately.This will not work with pure water because it is physically impossible to have water that contains an excess of OH (alkaline) without the presence of a charge-compensating metallic ion such as Na+ or Ca2+. Similarly, any water that is acidic (excess H+ ion) must contain a compensating impurity ion such as bicarbonate or sulfate. Thus ordinary drinkable water which contains only very low concentrations of metal ions will yield only weakly alkaline solutions.
Alkaline water is important for maintaining proper body pH and preventing acidosis.The pH of intracellular bodily fluids such as blood is controlled by an exquisitely-balanced set of reactions involving removal of (acidic) carbon dioxide through the lungs, removal of (alkaline) ammonia through the kidneys, and the buffering action within the blood by bicarbonate, and to a smaller extent by phosphate and certain proteins. In the most important of these mechanisms, carbon dioxide produced by cell metabolism reacts with water to form carbonic acid H2CO3, and this reacts with carbonate in the blood to form bicarbonate

H2CO3 + CO32– → 2 HCO3

which is carried by the blood to the lungs, where the carbon dioxide is then regenerated and expelled:

H2CO3 → CO2 + H2O

The pH of blood is especially critical and must be maintained within the range of about 7.35 – 7.45. If the blood pH falls outside this range the condition is known as acidosis or alkylosis. Temporary acidosis can be induced by holding your breath, preventing release of CO2. Temporary alkylosis can be induced by hyperventilation, causing excess release of CO2. Chronic acidosis or alkylosis can be very serious and is often associated with kidney failure.

The pH of ordinary drinking water will have little effect on the pH of the stomach contents because gastric fluid has an overwhelmingly low pH (Gastric fluid is essentially a dilute solution of hydrochloric acid.) Hundreds of millions of years of evolution have adapted humans to tolerate drinking waters having a fairly wide range of pH (5-8). Any water that is sufficiently alkaline to significantly affect gastric pH is unlikely to be considered potable by most people. Further, the enzymes that digest proteins in the stomach require a low pH in order to function properly, so if one were to ingest sufficient alkali to reduce gastric pH, it would also interfere with digestion.

If you really want (or need) to reduce gastric acidity, products such as Milk of Magnesia or Alka-Seltzer are cheaper and more effective than “water ionizer” machines. But bear in mind that acidosis and alkylosis are serious conditions that require medical intervention and can be properly diagnosed only by measurements of blood electrolyte and CO2 content.

The oxygen produced during electrolysis invigorates the body.The amount of oxygen that water can hold is very limited, and it is not significantly absorbed by the gut anyway. You can acquire far more oxygen by just taking an extra breath. For more on the myth of oxygenated waters, see the OxyScams page.
“Ionized water” acts as an effective antioxidant and free-redical fighter, and can even halt or reverse ageing.There is no reason to believe this. Some sales sites reveal their ignorance of chemistry by stating that the enhanced oxygen content causes the water to act as an anti-oxidant (any high-school chemistry student should be able to debunk this one!) It should also be pointed out that evolution has allowed our bodies to develop anti-oxidant enzymes such as peroxidase that are millions of times more efficient than anything that an electrolysis device could produce even if it did work! Finally, although anti-aging nostrums are widely marketed to the notoriously credulous seekers of alternative-health products, there is absolutely no evidence that any of these is effective; See The antioxidant myth: a medical fairy tale that was published in the 5 August 2006 New Scientist. See alsothis video that shows how the color of iodine is bleached by adding “alkaline water”; what’s really happening is that the hypochlorite ion in the water is oxidizing the iodine to [colorless] iodate ion.
