Quizplus · Accepted Answer

At pH 9, the hydroxide ion concentration is greater than the hydrogen ion concentration. The pH scale ranges from 0 to 14, where pH 7 is neutral (equal concentration of H+ and OH- ions). As the pH increases, the concentration of H+ ions decreases while the concentration of OH- ions increases, meaning that a pH of 9 has a higher concentration of OH- ions than H+ ions.
