Neutralization is a chemical reaction in which a base reacts with an acid to create water and a salt. In chemical terms, neutralization results from the interaction of ions in the acid and base. This reaction can occur between organic and inorganic compounds, between two inorganic compounds, between two organic compounds, and by adding a base to an acid or vice versa.

A chemical compound that has been neutralized is no longer either a base or an acid but a salt, while a neutralized solution has equal numbers of protonated and deprotonated forms of the solvent (forms in which protons have been added and taken away, respectively). When strong acids and bases interact, hydrogen ions (H⁺) combine with hydroxyl ions (HO^-) to form molecules of water.

A perfectly neutralized solution will have a pH of 7.0. In other words, the solution will be the salt dissolved in plain...
