Which term describes a reaction between an acid and a base?

• A. Neutralization
• B. Endothermic reaction
• C. Exothermic reaction
• D. Chemical equation

Answer: (A)

Neutralization is the reaction where an acid reacts with a base to form a salt and water. In water, the acid donates a proton (H+) and the base provides hydroxide (OH-); these combine to make water, while the leftover ions form the salt. A classic example is hydrochloric acid reacting with sodium hydroxide to yield sodium chloride and water. This name specifically describes the acid–base nature of the process, not other aspects like energy changes or how the reaction is written. Endothermic and exothermic describe heat flow, which can happen in a neutralization but aren’t the defining feature of the reaction type. A chemical equation is just the symbolic way to represent any reaction, not the type itself.
