The pH of a neutral solution is 7. At this pH, the solution has equal concentrations of both the H+ and OH- ions, which is 10^-7 mole/litre. The presence of both the hydrogen and hydroxyl ions in equimolar concentrations makes the solution neutral.
Balancing the pH in your body is key to maintaining good health. The pH is a measurement of the acid-alkaline ratio in the body and when this ratio is out of balance, many health issues may arise. A neutral pH is 7, below 7 is moving to the acidic side while above 7 is alkaline. A body that is acidic allows many disease processes to take hold and thrive.
