उत्तर
Neutralization is the process by which H+ ions of an acid react completely with the [OH]- ions of a base to give salt and water only.
Neutralization is simply a reaction between H+ ions given by strong acid and OH-ions given by strong base. In case of all strong acids and strong bases, the number of H+ and OH- ions produced by one mole of a strong acid or strong base is always same. Hence the heat of neutralization of a strong acid with strong base is always same.
