A pH of _____ is considered neutral.

A pH of 7 is considered neutral because it represents the point at which the concentrations of hydrogen ions (H⁺) and hydroxide ions (OH⁻) in a solution are equal. This is typically found in pure water at 25 degrees Celsius (77 degrees Fahrenheit). At this pH level, the solution is neither acidic (which would have a pH less than 7) nor basic (which would have a pH greater than 7). Understanding this concept is vital for various applications in water treatment and environmental science, as maintaining neutral pH levels is important for the health of aquatic ecosystems and the effectiveness of certain water treatment processes.
