The reaction NaOH + HCl → NaCl + H₂O represents:
Correct answer: C. Enthalpy of neutralization
- A. Enthalpy of reaction
- B. Enthalpy of formation
- C. Enthalpy of neutralization
- D. Enthalpy of combustion
Explanation
This equation shows the reaction of a strong acid (HCl) with a strong base (NaOH) to produce a salt (NaCl) and water. The enthalpy change associated with this specific type of acidbase reaction is called the enthalpy of neutralization.
