Why does water have a pH of 7?
Even in pure water ions tend to form due to random processes (producing some H+ and OH- ions). The amount of H+ that is made in pure water is about equal to a pH of 7. That’s why 7 is neutral. In pure water near room temperature, the concentration of H+ is about 10-7 moles/liter, which gives a pH of 7.
