Question

Quizplus · Accepted Answer

A solution that contains equal numbers of hydrogen ions (H+) and hydroxide ions (OH-) is neutral, with a pH of 7. This is because these ions react with each other to form water (H+ + OH- -> H2O), leaving no excess of either ion to contribute to acidity or basicity.
