But there are actually a few benefits. According to a study in the Annals of Otology, Rhinology & Laryngology, alkaline water with a pH of 8.8 can help sooth acid reflux because the higher pH level kills pepsin, an enzyme involved in breaking down food proteins and a main cause of acid reflux.

Alkaline water is different from tap because it's less acidic—it has a pH over seven, meaning that it has a lower concentration of hydrogen ions, explains Alyse Levine, R.D., founder of the Eating Reset Plan. Time for a basic chemistry lesson: All liquids have a measure of acidity, which is determined on the pH scale.

Infographic: 5 common drinking water concerns. The pH scale ranges from 0 to 14 with a pH of 7 being neutral. A pH less than 7 is acidic and a pH greater than 7 is alkaline. The pH scale is logarithmic so for every one unit of change in pH there is a tenfold change in ion concentration. This means a solution with a pH of 3 is 10 times more acidic than a solution with a pH of 4 and 100 times more acidic than one with a pH of 5.

The effects on the pH scale from drinking DRO water. Highly purified DRO water is neutral with a pH of 7. Since there are virtually no dissolved solids (TDS) in this water, there is nothing to influence the pH change in either the alkaline or acid direction or to act as buffers to resist change.

Although it can be slightly acidic depending on its source, water usually is considered neutral on the pH scale, having a pH of 7. Alkaline water has a pH of approximately 8. The exact pH level depends largely on the brand or the equipment used to alkalize the water.

Alkaline water, also known as ionized water, is a beverage that is neither acidic nor neutral on the pH scale, having a level above 7. It is available through commercial or home systems and is also sold in bottles.

Alkaline water is not just about the pH of the water. If it was all about pH, all you'd have to do to achieve that is add pH drops to your tap water. Alkaline water is about much more than pH; it's ionized pH water. That means it has an oxidant reduction potential (ORP), that makes it an antioxidant more powerful than green tea. Like many, I didn't know that. So I wanted to add it to this discussion.

What is the difference between naturally and artificially alkaline water? When measured in drinking water, an alkaline pH can be a result of either natural or unnatural conditions in the water. Thus when comparing two waters, each with a pH of 9.5, one can be healthful while the other causes side effects. Water ionizers split apart water molecules with electricity to artificially create alkaline water.

Alkaline water can be consumed from many sources, including special filters, faucet attachments, and additives that raise the pH. One of the most common (and convenient) ways, though, is through bottled water (such as Essentia or Evamor), sold at most grocery stores.

The pH measures the concentration of hydrogen ions in the liquid, which is expressed on a scale of 0-14. Anything under seven (think black coffee, orange juice, and vinegar) is acidic, seven is neutral and above seven (like baking soda) is alkaline territory, says Levine.

what is the ph of alkaline water
The pH of alkaline water is greater than 7.
