Question

Which of the following is a neutralization reaction?

1) NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)
2) Fe₂⁺O₃ + HCl → FeCl3 + H₂O
3) AgNO₃ + HCl → AgCl + HNO₃
4) Pb(NO₃)2 + 2KI → PbI₂ + 2KNO₃

Answer 1

Option 1) NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l) is a neutralization reaction.

Step-by-step explanation:

The neutralization reaction is a type of chemical reaction that occurs between an acid and a base, resulting in the formation of water and a salt. Among the options provided, option 1) NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l) is a neutralization reaction. In this reaction, sodium hydroxide (NaOH), a base, reacts with hydrochloric acid (HCl), an acid, to produce sodium chloride (NaCl) and water (H₂O).
