Neutralization

Neutralization- the reaction between an acid and a base, producing a salt and water; 

hydrochloric acid and sodium hydroxide form sodium chloride and water

HCl_(aq) + NaOH_(aq) → H₂O_(l) + NaCl_(aq)

Neutralization is the basis of titration, where a pH indicator shows equivalence point when the equivalent number of moles of a base have been added to an acid.
