Principle
When a strong acid is neutralised with a strong base in dilute
solution, the same amount of heat is always released. If the
reaction takes place under isobaric conditions, this heat is known
as the enthalpy of neutralisation. The chemical reaction which
generates this heat is the reaction of protons and hydroxyl ions to
form undissociated water. It therefore correlates to the enthalpy
of formation of water from these ions.
