Ph Scale (Noun)
Meaning
(from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than 7 is more acidic).
Classification
Nouns denoting attributes of people and objects.
Examples
- The pH scale is used to measure the acidity or alkalinity of a solution, with a pH of 7 being neutral.
- A pH scale reading of 3 indicates a strongly acidic solution, while a reading of 11 indicates a strongly basic solution.
- The pH scale is logarithmic, meaning that each whole number change represents a tenfold change in hydrogen-ion concentration.
- To determine the pH of a solution, a pH scale is often used in conjunction with pH indicator strips or pH meters.
- The pH scale ranges from 0 to 14, with values below 7 indicating acidity and values above 7 indicating alkalinity.
