WebMar 16, 2024 · The pH scale (pH) is a numeric scale used to define how acidic or basic an aqueous solution is. It commonly ranges between 0 and 14 but can go beyond these values if sufficiently acidic/basic. The pH value is logarithmically and is inversely related to the concentration of hydrogen ions in a solution. WebTo calculate pH, you should know the concentration of hydrogen ions (H +) in your solution. From there, the pH can be found by: p H = − log 10 ( [ H +]) Since this is a logarithmic calculation, in order to change the pH by one unit (say, from 2 to 3), the concentration of H + must be changed by 10 times (say, from 0.01 mol/L to 0.001 mol/L).
