What is the pH value of a neutral solution?

The pH value of a neutral solution is 7. This value indicates a balanced concentration of hydrogen ions (H+) and hydroxide ions (OH-) in the solution. In pure water, which is commonly used as a reference, the concentration of H+ and OH- ions is equal, resulting in a pH of 7.

In the context of the pH scale, which ranges from 0 to 14, values below 7 denote acidic solutions, while values above 7 indicate alkaline (or basic) solutions. Understanding that a pH of 7 signifies neutrality is fundamental in various fields, including public health, as it helps assess the potential safety of water and other substances for human consumption and environmental impact.
