decreasing the concentration of OH– ions

1 answer

To decrease the pH of a base in a solution at equilibrium, you would want to decrease the concentration of hydroxide ions (OH⁻) in the solution. This is because pH is inversely related to the concentration of hydrogen ions (H⁺) and directly related to the concentration of OH⁻ ions in the context of basic solutions.

Therefore, the correct response is:

decreasing the concentration of OH– ions.
