A neutralization reaction combines a strong acid with a strong base to form a neutral salt and water. The process is also known as a double displacement reaction.
Neutralization reactions only occur through strong acids and bases. Weak acids and bases do not undergo these reactions. Since the reactions that occur are also double displacement reactions, the cation from the acid reacts with the anion or the base, or the anion from the acid reacts with the cation of the base. Neutralization reactions do not form any spectator ions and do not form any other products besides salt and water.
