Is adding acid to water endothermic or exothermic?
First, adding more acid releases more heat, as it is exothermic. If you add water to acid it forms an extremely concentrated solution of acid initially. So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container and all this because the reaction is exothermic.

Answer:
Explanation:
When an acid is dissolved in water, the energy absorbed due to its dissociation is lesser than the energy released due to hydration of resultant ions. Therefore, the net process is exothermic i.e. energy is released when acid is dissolved in water. Therefore, the process of adding acid to water is exothermic.
