The concentration of hydrogen ions in water is expressed as pH, which is approximately equal to the negative base-ten logarithm of the hydrogen ion concentration. As a reminder, the scale runs from 0 (very ,strong, acid) to 14 (very ,strong, alkali). A pH of 7 indicates a solution is neutral, neither acidic nor alkaline.
