To raise the pH of a solution from 5 toward neutrality, which option would you add?

Explanation:
Raising pH toward neutrality means reducing the solution’s acidity by lowering the hydrogen ion concentration, often through dilution with a neutral substance. Water is neutral and will dilute the acidic solution without adding more H+, so it moves the pH closer to 7. The other options introduce extra hydrogen ions and are acidic, which would push the pH lower rather than raise it.
