The pH Scale of Common Chemicals - Science Notes and Projects
Sep 30, 2020 · The pH scale shows how acidic or basic a chemical is in aqueous solution (mixed with water). The scale runs from 0 (most acidic) to 14 (most alkaline or basic), where 7 is neutral pH. Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater than 7 up to 14 are bases.
PH | Definition, Uses, & Facts | Britannica
PH, 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 into numbers between 0 and 14. Learn more about pH.
pH - Wikipedia
The pH scale is logarithmic and inversely indicates the activity of hydrogen ions in the solution. where [H +] is the equilibrium molar concentration of H + (M = mol/L) in the solution. At 25 °C (77 °F), solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic.

Explainer: What the pH scale tells us - Science News Explores
Mar 5, 2020 · The pH scale measures whether there is more hydronium or hydroxide in a solution. In other words, it tells us how basic or acidic the solution is. A lower pH means something is more acidic, also known as a stronger acid.

16.4: The pH Scale - Chemistry LibreTexts
The pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times more acidic than a pH of 4. Likewise, a pH of 3 is one hundred times more acidic than a pH of 5.
