WebHow is pH measured? Show transcribed image text Expert Answer pH of a solution says about the concentration of H+ ion in it. It has a range of 0 to 14 . If pH of a solution is greater than 7 it means the solution is basic in nature and if pH is less than 7 it means the … WebThe 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.

Web7 sep. 2024 · Our definition of acids and bases normally relies on referencing the pH scale, with 7 pH in standard conditions being neutral, meaning the solution has an equal ratio of H 3 O + : OH – . Below 7 pH is acidic, meaning there is more H 3 O + than OH –, and vice versa above 7 pH. Outside of standard conditions, these assumptions no longer apply.
