Enthalpy Change of Neutralisation

The standard enthalpy change of neutralisation ΔneutHθ is the energy change that accompanies the reaction of an acid with a base to form one mole of water H2O (l) under standard conditions, all reactants and products being in their standard states.The ionic equation for the reaction is:H+(aq) + OH-(aq) → H2O (l)
