The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Components**: Begin by recognizing that the question involves an aqueous solution of sodium chloride (NaCl). Sodium chloride is a salt formed from the reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH). 2. **Dissociation in Water**: When NaCl is dissolved in water, it dissociates into its constituent ions: - NaCl → Na⁺ + Cl⁻ This means that in an aqueous solution, we have sodium ions (Na⁺) and chloride ions (Cl⁻) present. 3. **Neutrality of the Solution**: In addition to NaCl, water (H₂O) also dissociates into hydrogen ions (H⁺) and hydroxide ions (OH⁻): - H₂O ⇌ H⁺ + OH⁻ The presence of these ions is crucial for determining the nature of the solution. 4. **Reaction of Ions**: The Na⁺ ion does not react with water, but the Cl⁻ ion, being the conjugate base of a strong acid (HCl), does not affect the pH significantly. Similarly, the Na⁺ ion, being the conjugate acid of a strong base (NaOH), also does not affect the pH. 5. **Conclusion**: Since neither ion affects the pH of the solution significantly, the overall solution remains neutral. Therefore, an aqueous solution of NaCl is classified as a neutral solution. 6. **Final Answer**: The type of an aqueous solution of NaCl is neutral. ---
