Neutralization is the basis of titration. There are several different types of acid/base titrations. For example, when sodium hydroxide is added to acetic acid, the sodium hydroxide will react with and consume the acetic acid based on the following neutralization reaction: CH. In a reaction in water,neutralization results in there being no excess of hydrogen or hydroxide ions present in solution.
