Quizplus · Accepted Answer

The higher the concentration of hydroxide ions (OH-) in a solution, the higher its pH. NaOH is a strong base that dissociates almost completely in water, producing a high concentration of OH- ions. Therefore, a 2.0 M NaOH solution will have the highest pH compared to the other options.
