increasing the initial concentration of solute

Answer 1

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. The pH scale is inversely related to the concentration of hydrogen ions (H⁺) and is affected by the concentration of hydroxide ions in that more hydroxide leads to a higher pH (more basic).

Therefore, the correct response is:

decreasing the concentration of OH⁻ ions
