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).
Bases and acids are seen as opposites because the effect of an acid is to increase the hydronium (H3O+) concentration in water, whereas bases reduce this concentration. A reaction between an acid and base is called neutralization. In a neutralization reaction, an aqueous solution of a base reacts with an aqueous solution of an acid to produce a solution of water and salt in which the salt separates into its component ions.
