Answer:
It commonly ranges between 0 and 14, but can go beyond these values if sufficiently acidic/basic. pH is logarithmically and inversely related to the concentration of hydrogen ions in a solution. The pH to H + formula that represents this relation is: The solution is acidic if its pH is less than 7.
