What does a base do in a solution?

A base in a solution has the characteristic function of removing hydrogen ions (H+) from the solution, which effectively decreases the concentration of H+ ions present. When a base is dissolved in water, it typically either releases hydroxide ions (OH-) or reacts with H+ ions, promoting a lower concentration of H+ and resulting in a higher pH.

As H+ ions are removed, this shifts the balance of the solution towards a more alkaline environment, thus increasing the pH. This fundamental property of bases is what differentiates them from acids, which increase H+ concentration and lower pH. Understanding the behavior of bases is key in acid-base chemistry, as they play a vital role in various biological processes and chemical reactions.
