The reaction NaOH + HCl giving NaCl and water is a typical example of which type of reaction?
APrecipitation reaction
BSingle displacement reaction
CPhoto decomposition reaction
DNeutralization reaction
Answer & Solution
Correct answer: D. Neutralization reaction
1. The reactants are a base, sodium hydroxide, and an acid, hydrochloric acid.
2. An acid reacting with a base to form a salt and water is a neutralization reaction.
3. A precipitation reaction would instead form an insoluble solid, which does not happen here since NaCl is soluble.
4. Therefore it is a neutralization reaction.
