The PH Scale & Water

In chemistry, we are taught that pH is a measurement of the concentration of hydrogen ions in a water-based solution. A lower pH means that there are more hydrogen ions in the liquid, whereas a higher pH indicates fewer hydrogen ions in the liquid.

In simple terms, pH is a scale from 1 to 14 that measures the acidity or alkalinity of a liquid. In the middle of the scale is pure distilled water, with a neutral pH of 7. Anything with a pH below 7 is an acid, and anything with a pH above 7 is an alkali, or base.

To use everyday examples, vinegar is very acidic, with a pH of about 2. Conversely, bleach is highly alkaline, with a pH of about 13.5.

The U.S. Environmental Protection Agency recommends that the pH level of water sources should be at a pH measurement level between 6.5 to 8.5 on a scale that ranges from 0 to 14.

What is the pH level of your drinking water at home?
