A salt is formed when a cation (positive ion) of an acid forms a compound with the anion (negative ion) of a base. The neutralization of a strong acid and a strong base results in a solution with a pH of 7 (neutral pH).
A neutralization reaction is a specific type of double replacement reaction. A neutralization reaction occurs when an acid reacts with an equal amount of a base. This usually creates a solution of a salt and water. For example, hydrochloric acid reacts with sodium hydroxide to produce sodium chloride and water:
