Which of the following describes a base's effect on pH?

Bases raise the pH of a solution. pH indicates how acidic or basic a solution is: below 7 is acidic, 7 is neutral, and above 7 is basic. Bases increase hydroxide ions (OH−) and react with hydrogen ions (H+) to form water, which lowers the H+ concentration. With fewer H+ ions, the solution becomes less acidic and the pH climbs above 7. Therefore, a base’s effect on pH is to produce a pH greater than 7.
