Answer

Neutralization Explanation 1. Identify the reaction type. In this reaction, HNO₃ (a strong acid) reacts with NaOH (a strong base) to produce water (H₂O) and a salt (NaNO₃). Reactions between an acid and a base that produce a salt and water are classified as **neutralization reactions**. 2. Analyze the options provided. Let's examine the options: 1. **Weak acid dissociation**: This would involve the dissociation of a weak acid into its ions. This is incorrect because HNO₃ is a strong acid. 2. **Weak base dissociation**: This would involve the dissociation of a weak base into its ions. NaOH is a strong base, so this is incorrect. 3. **Strong base dissociation**: This would involve the dissociation of NaOH into Na⁺ and OH⁻. While NaOH dissociates in solution, this is not the overall reaction described. 4. **Strong acid dissociation**: This would involve the dissociation of HNO₃ into H⁺ and NO₃⁻ ions. While HNO₃ dissociates in solution, this is not the focus of the overall reaction. 5. **Neutralization**: This involves an acid reacting with a base to form a salt and water, which matches the given reaction. 3. Select the correct answer. Among the options, the reaction is best classified as **neutralization**, as it involves the combination of a strong acid and a strong base to form water and a salt.
