The enthalpy of neutralisation of NaOH with HCl is 57.1 kJ mol-1 while with CH3COOH, it is 56.1 kJ mol-1
This happens because:
- acetic acid is an organic acid
- acetic acid is little soluble in water
- acetic acid is a weak acid and requires lesser sodium hydroxide for neutralisation
- some heat is required to ionize acetic acid completely.
Answer
(D) some heat is required to ionize acetic acid completely.
