Quizplus · Accepted Answer

pH 14 has the highest concentration of hydroxide ions because pH is a measure of the concentration of hydrogen ions (H+) in a solution. By definition, a pH of 14 has a concentration of 10^-14 moles of H+ per liter of solution. This means that the concentration of hydroxide ions (OH-) is 10^-14 moles per liter, which is the highest concentration of the options given.
