Hint :During the process of dissolving an acid or base in water, $ {{H}^{+}} $ and $ O{{H}^{-}} $ ions are produced in the product side. Due to the production of the ions in the product side, a huge amount of heat is evolved.

Complete Step By Step Answer:
Now, when acid or base is dissolved in water, $ {{H}^{+}} $ and $ O{{H}^{-}} $ are released in the product side of the reaction. Due to the ions being produced in the product side, a huge amount of heat is evolved which makes the reaction highly exothermic.
One factor that also helps in releasing energy is the energy released when bonds are formed between the product compounds.
When any bond is broken, energy is taken into the reaction and when a bond is made, energy is released out of the reaction.
The release or taking of energy depends upon the bond energies of ions and energy of solvation. For acids and bases, the energy of solvation is much higher than the bond energy, thus a lot of energy is released.
And, due to the release of a lot of energy, heat is released in a huge amount. Thus, the temperature of the reaction increases.
True, the process of dissolving an acid or base in water is a highly exothermic one.


Note :
The amount of heat released depends on more than one factor. It depends on the ions released at the product side and due to the energy released in the product side.
