heat of neutralization

The heat of neutralization of all strong acids and bases are the same in dilute solution. It can be explained easily on the basis of this theory. According to this theory, the strong acids and bases are completely ionised in solution. They combine to form a highly ionised salt and feebly ionised water and since in all cases water is formed, the heat produced should be same. Heat of neutralization is, in fact, the heat of formation of water from H+ and OH" ions, which is always the same irrespective of the nature of acids and bases.H+ + CI" + Na+ + OH" Na+ + CF + H20 + 13-7k calsor H+ + OH"—»H20 + 13-7 k cals
