At what pH value is a solution considered neutral?

A solution is considered neutral at a pH of 7 because this value represents the point at which the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-) in the solution. At this pH, the solution is neither acidic nor basic.

The pH scale ranges from 0 to 14, where a pH less than 7 indicates acidity (greater concentration of H+), and a pH greater than 7 indicates alkalinity (greater concentration of OH-). Understanding the concept of neutrality in relation to pH is fundamental in various fields, including chemistry and environmental science, as it helps in assessing the acidity or basicity of solutions, which can significantly affect chemical reactions and biological processes.
