Characteristics that can be determined without a chemical reaction and that do not cause a chemical change in the substance.
The term pH refers to the concentration of hydrogen ions in water. Measured on a scale of 0 to 14, neutral water has a pH of 7, acids have a pH of less than 7, and bases have a pH greater than 7. While the desired pH for drinking water typically hovers around 7.0, the acceptable range for the pH of drinking water is between 6.5 and 8.5.
