If the pH of a solution is between 5 and 7, how is the solution classified?

A solution with a pH between 5 and 7 is classified as a weak acid. The pH scale ranges from 0 to 14, where a pH of 7 is considered neutral, which corresponds to pure water. Values below 7 indicate acidity, while values above 7 indicate alkalinity.

In this case, a pH of 5 represents a mildly acidic solution, which aligns with the characteristics of weak acids. Weak acids only partially dissociate in water and produce fewer hydrogen ions compared to strong acids. Therefore, the presence of a pH value within the specified range signals that while the solution exhibits acidic properties, it is not strong enough to be classified as a strong acid. This classification is important in understanding how different substances interact chemically and can influence treatments or products in a cosmetic or health setting.
