Question

Quizplus · Accepted Answer

The pH of a solution is a measure of the concentration of free hydrogen ions (H+) in the solution. A pH of 7 is considered neutral, indicating an equal concentration of H+ and hydroxide (OH-) ions. Lower pH values indicate higher acidity, with a higher concentration of H+ ions, while higher pH values indicate alkalinity or basicity, with a higher concentration of OH- ions.
