Web2 mrt. 2024 · pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Web9 jan. 2024 · The pH is defined as the negative, base 10 logarithm of the hydrogen ion concentration. That is: pH = -log [H + ]. Thus, a hydrogen ion concentration of 0.00000001 mole/L (10 -8 M) becomes pH 8: pH = -log (10 -8 M) = -log (-8) = 8. Pure water has a hydrogen ion concentration of 10 -7 mole/L (pH 7).
