Respuesta :

The enthalpy of solutionenthalpy of dissolution, or heat of solution is theenthalpy change associated with the dissolution of a substance in a solvent at constant pressure resulting in infinite dilution. The enthalpy of solution is most often expressed in kJ/mol at constant temperature. 

Explanation:

Enthalpy of a solution is defined as the sum of lattice energy and hydration energy of a solution.

Symbol which represents enthalpy is [tex]\Delta H[/tex].

This enthalpy of a solution can have either a positive or negative value. A positive value of enthalpy means that the reaction takes place is endothermic in nature.

On the other hand, a negative value of enthalpy means that the reaction takes place is exothermic in nature.
