Here's why:
* Acids have a pH lower than 7, indicating a higher concentration of hydrogen ions (H+).
* Bases have a pH higher than 7, indicating a lower concentration of hydrogen ions (H+).
When an acid and base react, they neutralize each other. This neutralization process involves the hydrogen ions (H+) from the acid combining with hydroxide ions (OH-) from the base to form water (H2O). This reaction reduces the concentration of both H+ and OH-, bringing the solution closer to a neutral pH of 7.
