Question

What is the notation for the enthalpy of solution?

Answer 1

Explanation:

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

Symbol which represents enthalpy is $\Delta H$.

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.

Answer 2

The enthalpy of solution, enthalpy 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.
