What is Hydration?

Hydration is the process by which water molecules surround and interact with dissolved ions or polar molecules through electrostatic attraction and hydrogen bonding. The hydration energy (enthalpy of hydration) released when an ionic compound dissolves is a major driving force for solubility. In organic chemistry, hydration also refers to the addition of water across a double bond.
