Final answer:
Removing H+ ions from a solution increases the pH, making the solution more basic.
Step-by-step explanation:
The pH decreases as the concentration of H3O+ ions increases because the reciprocal of the H3O+ concentration is used in the pH calculation. The larger the given number, the smaller the reciprocal, resulting in a lower pH value. Therefore, removing H+ ions from a solution increases the pH, making the solution more basic.
