Tag: Solvation

Did you know that water is the most commonly used solvent in chemistry? Understanding what is the definition of hydration in chemistry is fundamental to comprehending how many substances, especially ionic compounds, dissolve and react in this universal solvent.

The enthalpy of hydration, also known as hydration energy, is always a negative value, meaning the process is exothermic. Understanding the **energy change of hydration** is fundamental to explaining why some salts release heat when they dissolve in water, while others absorb it.
