Web1. 14. The pH scale covers the active concentration of the H + ions and OH - ions and therefore the pH unit of measure is defined as the negative common logarithm of the active hydrogen ion concentration in an aqueous solution. If the H + ion concentration changes by a factor of ten, the pH value changes by one unit. WebSep 9, 2024 · The pH scale is a familiar concept for students who study science. The pH value of a solution reflects the relative concentration of hydrogen ions (H+) or protons to the concentration of hydroxide ions (OH-) in a solution. Solutions with a pH value less than 7 are acidic and those with a value greater than 7 are basic, or alkaline.
