A solution with a pH of 14 is classified as?

A solution with a pH of 14 is classified as a strong alkali, which is characterized by a high concentration of hydroxide ions (OH-) in the solution. The pH scale ranges from 0 to 14, with values below 7 indicating acidity, values of 7 being neutral, and values above 7 indicating alkalinity. Specific to this classification, a pH of 14 represents the highest level of alkalinity, indicating a solution that is highly basic and capable of neutralizing acids effectively.

In contrast, neutral solutions have a pH of 7, strongly acidic solutions have a pH below 7, and weak acids are characterized by a pH closer to 7 but still below it, showing that they do not completely dissociate in water. Therefore, a pH of 14 distinctly signifies a strong alkali rather than any of the other classifications mentioned.
