Final answer:
The reaction between aqueous HCl and solid NaOH produces aqueous NaCl and liquid H₂O, which is a neutralization reaction resulting in a salt and water.
Step-by-step explanation:
The product of the reaction between aqueous hydrochloric acid (HCl) and solid sodium hydroxide (NaOH) is aqueous sodium chloride (NaCl) and liquid water (H₂O). This reaction is a classic example of a neutralization reaction where an acid reacts with a base to produce a salt and water. The balanced chemical equation for this reaction is:
HCl(aq) + NaOH(s) → NaCl(aq) + H₂O(l)
In more detail, the ions involved are H+ (aq) and OH− (aq), which combine to form water, H₂O(l), while the Na+ and Cl− ions remain in solution as aqueous sodium chloride. Consequently, the correct answer to the student’s question is 1) Aqueous sodium chloride (NaCl) and liquid water (H₂O).
