1. Dissolution reaction

The change in enthalpy of the dissolution reaction, Δ _dis H, of an inorganic compound is equal to the heat of the dissolution reaction at constant pressure, to the nearest sign.

Thus the enthalpy of dissolution of aluminum bromide in water according to the reaction : $Al {Br}_{3} (s) + H_{2} O (l) \to Al {Br}_{3} (l) + H_{2} O ($
