why the process of dissolving an acid or a base in water is a highly exothermic reaction
Answers
there's a slight concept here. so every time a bond breaks, energy is taken and every time a bond is formed, energy is released. total energy which we see= energy released- energy taken for the reaction now, coming to the question, depending on the bond energies of ions and their energy of solvation, the compound may release or take energy. in the case of strong acids and bases, the energy of solvation is much higher than the bond energy. thus, a lot of energy is released.
Answer: The process of dissolving is exothermic when more energy is released when water molecules “bond” to the solute than is used to pull the solute apart. Because more energy is released than is used, the molecules of the solution move faster, making the temperature increase.
