How does a base interact with hydrogen ions in a solution?

A base interacts with hydrogen ions in a solution by effectively decreasing the hydrogen ion concentration. This occurs because bases, which are substances that can accept protons (H⁺ ions), react with hydrogen ions present in the solution.

When a base is added to an acidic solution, it reacts with the hydrogen ions, thus lowering their concentration. This reaction leads to the formation of water or other products that do not contribute to the hydrogen ion concentration, resulting in an overall increase in pH, which signifies a more basic or neutral environment.

In this process, the base essentially neutralizes the acidity of the solution by alleviating the presence of hydrogen ions, leading to a decrease in their overall concentration.
