A pH of 7 is defined as neutral, which indicates that the concentration of hydrogen ions (H⁺) in the solution is equal to the concentration of hydroxide ions (OH⁻). In the pH scale, which ranges from 0 to 14, values below 7 represent acidic conditions, wherein there are more hydrogen ions present, while values above 7 indicate basic (or alkaline) conditions, characterized by an excess of hydroxide ions. The neutrality at a pH of 7 means that it is the point of balance between acidity and alkalinity. This is particularly important in wastewater treatment and environmental science, as maintaining a neutral pH is vital for effective chemical and biological processes.
