Understand the Arrhenius acid-base theory: an Arrhenius acid increases the concentration of H\(\textsuperscript{+}\) ions in aqueous solution, while an Arrhenius base increases the concentration of OH\(\textsuperscript{−}\) ions.
Recognize that when an Arrhenius acid and an Arrhenius base react, the H\(\textsuperscript{+}\) ions from the acid combine with the OH\(\textsuperscript{−}\) ions from the base.
This combination forms water (H\_2O), which is a key characteristic of the reaction between an acid and a base in this theory.
Additionally, the acid and base typically form a salt as a product alongside water.
This type of reaction, where an acid and a base react to form water and a salt, is called a neutralization reaction.
