A solution with a pH of 7 (at 25°C) is classified as :
Neutral
The pH scale runs from 0 to 14 at 25°C, with values below 7 indicating acidic solutions and values above 7 indicating basic (alkaline) solutions.
A pH of exactly 7 means the concentration of hydrogen ions (\(H^+\)) equals the concentration of hydroxide ions (\(OH^-\)) in the solution, which is the defining condition of neutrality, as seen in pure water at 25°C.
Therefore, a solution with a pH of 7 is classified as neutral.
