What is the measure on the pH scale measuring?
measure of how acidic/basic water is. The range goes from 0 – 14, with 7 being neutral
The pH scale measures the acidity or alkalinity of a solution. It is a scale that ranges from 0 to 14, with 0 being the most acidic, 7 being neutral, and 14 being the most alkaline or basic. The pH scale is based on the concentration of hydrogen ions (H+) in a solution. A solution is considered acidic when it has a pH less than 7, and it is considered basic or alkaline when it has a pH greater than 7. A change of one unit on the pH scale represents a ten-fold change in the concentration of hydrogen ions, which means a solution with a pH of 3 is ten times more acidic than a solution with a pH of 4.
