pH of Water - Environmental Measurement Systems
pH of Water - Environmental Measurement Systems

This determination is due to the effect of hydrogen ions (H+) and hydroxyl ions (OH-) on pH. The higher the H+ ,concentration,, the lower the pH, and the higher the OH- ,concentration,, the higher the pH. At a neutral pH of 7 (pure water), the ,concentration, of both H+ ions and OH- ions is 10⁻⁷ M.
