Final answer:
A neutralization reaction occurs when an acid and a base combine to form water and a salt.
Step-by-step explanation:
A neutralization reaction between an acid and a base occurs when the reactants, HX and YOH, combine to form products, YX and H₂O. In this reaction, the acid donates a proton (H+) to the base, resulting in the formation of water and a salt. The presence of water and the production of a salt indicate that this is a neutralization reaction.
