Question

define enthalpy of neutralization and give its value for strong acid and strong base reaction

Answer 1

The standard enthalpy change of neutralisation is the enthalpy change when solutions of an acid and an alkali react together under standard conditions to produce 1 mole of water. Notice that enthalpy change of neutralisation is always measured per mole of water formed.

Answer 2

The enthalpy of neutralization (ΔHn) is thechange in enthalpy that occurs when one equivalent of an acid and one equivalent of a base undergo a neutralization reaction to form water and a salt. It is aspecial case of the enthalpyof reaction. It is defined asthe energy released with theformation of 1 mole of water.
