Step-by-step explanation:
A chemical reaction in which acid is added to base and this leads to the formation of salt and water is known as a neutralization reaction.
For example,

Here, sodium chloride (NaCl) is the salt formed due to chemical reaction between HCl and NaOH.
Basically, in this type of reaction acid is neutralized by the addition of a base.
Thus, we can conclude that when an acid such as hcl reacts with a base such as naoh, the products are a salt (nacl) and water (h2o) then neutralization is the term which best describes this type of chemical reaction.
