Why is the reaction of an acid and a base called neutralization?

If Hydrochloric acid (with a PH of around 1) is added to Sodium Hydroxide

(with a PH of around 14), if the quantities are even then the end product will have a PH close to 7 (A neutral PH). This is why it is called Neutralization

Put another way, if the proper amount and concentration of an acid and a base are mixed, the two will completely react to form a salt and water.

e.g. the reaction between hydrochloric acid and sodium hydroxide:

HCl + NaOH --> H2O + NaCl

Water has a pH of 7. So does sodium chloride. Therefore, the resulting solution is neutral.
