Bookmark or Share- pH and Water | U.S. Geological Survey - USGS.govpH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. The pH of water is a very important measurement concerning water quality.
- pH - WikipediaIn chemistry, pH ( / piːˈeɪtʃ / pee-AYCH ), also referred to as acidity or basicity, historically denotes " potential of hydrogen " (or "power of hydrogen"). [1] . It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions.
- pH Scale: Acids, bases, pH and buffers (article) | Khan AcademyThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.
- PH | Definition, Uses, & Facts | BritannicapH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions. The term, widely used in chemistry, biology, and agronomy, translates the values of the concentration of the hydrogen ion—which ordinarily ranges between about 1 and 10 −14 gram-equivalents per litre—into numbers between 0 and 14.

The relationship between acid strength and the pH of a solution. Key points. We can convert between [ H +] and pH. using the following equations: pH = − log. [ H +] [ H +] = 10 − pH. We can convert between [ OH −] and pOH.
