The pH of a solution is 9.0. Is it acidic, basic, or neutral?

Explanation:
Understanding pH shows how acidic or basic a solution is: lower numbers mean more acidic, a pH of 7 is neutral, and higher numbers mean more basic. A pH of 9 means the solution has less hydrogen ion activity than neutral water and is alkaline, so it is basic. It’s not acidic because pH is above 7, and it’s not neutral. Amphoteric describes a substance that can act as both an acid and a base, not the current pH classification of the solution.
