Verified step by step guidance

Understand that pH is a measure of the hydrogen ion concentration in a solution. A higher pH indicates a lower concentration of hydrogen ions, making the solution more basic.

Recognize that bases are substances that can accept hydrogen ions (H+) or donate hydroxide ions (OH-). This action reduces the concentration of hydrogen ions in the solution.

Identify that increasing the concentration of hydroxide ions (OH-) in a solution will lead to a decrease in hydrogen ion concentration, as OH- ions can combine with H+ ions to form water (H2O).

Realize that decreasing the concentration of hydrogen ions (H+) directly increases the pH, as pH is inversely related to the concentration of hydrogen ions.

Conclude that bases work to increase the pH of a solution by both increasing the concentration of hydroxide ions and decreasing the concentration of hydrogen ions, which corresponds to options a and b.
