What is a neutralization reaction in acid-base chemistry?

• A. Reaction between an acid and a base to form salt and water.
• B. Reaction of an acid with a metal to produce hydrogen gas.
• C. Reaction of a base with water to form hydroxide ions.
• D. Reaction of a salt and water to form acid and base.

Answer: (A)

Neutralization is an acid-base reaction where an acid donates a proton (H+) and a base provides hydroxide (OH−), and they combine to form water while the remaining ions form a salt. This is why the reaction typically ends with salt and water. For example, hydrochloric acid reacting with sodium hydroxide gives sodium chloride and water. The other described processes don’t fit neutralization: reacting an acid with a metal produces hydrogen gas, a base reacting with water shows how bases create OH− but isn’t a neutralization, and a salt reacting with water to form acid and base is the reverse or hydrolysis, not neutralization.
