Question

Quizplus · Accepted Answer

pH is a measure of the concentration of hydrogen ions (H+) in a solution, and is expressed as a numerical value on a scale from 0 to 14. A high concentration of hydrogen ions (low pH) indicates acidity, while a low concentration of hydrogen ions (high pH) indicates alkalinity. Sodium content of body fluids and amounts of carbon dioxide are not directly related to pH.
