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.
A neutral solution has a pH value of exactly 7 (at 25oC). See the Related Questions to the for more information about acids, bases and the pH scale. Neutral is neither acid (â¦ 7), hence the name neutral The pH value of 7.0 is considered to be neutral. Pure water has a pH of 7.0   Typically a pH of 7 is considered neutral since it is the pH of water. 7 Actually that's at 25 Degree C At 37 degrees C (body temp) its 7.4. 17 people found this useful.
