pH equal to 7 is considered to be neutral. This is the pH of pure water at a temperature of 25 °C.

pH is a logarithmic scale based on the concentration of protons(H+) in the solution. Thus, a change of pH by 1 corresponds to a change in concentration by a factor of 10. In general, the pH of most substances varies from 0 to 14 although for some extreme cases the pH can be greater than 14 or less than 0.
