But if water The molecule itself or the original substance molecule itself has changed, for example, water has broken down into hydrogen atom, oxygen atom or hydroxyl, or Hydrogen ion 、 Hydroxyl radical When combined with raw material molecules New substances 。 organic compound Double bond or Triple bond During hydration, it will break and add water molecule fragments to generate new substances. as ethylene Will become ethanol ； Acetylene will be hydrated into acetaldehyde Etc.

Hydration

The combination of solute molecules or ions with solvent molecules is called Solvation , generating Hydrated molecule （ Hydrated ion ）, this process liberate heat 。 For aqueous solution, this action is called hydration, and most of it belongs to chemical change. However, if only Ionic bond If there is no new bond formation, then this part of hydration does not belong to chemical change. If salt is dissolved in water Chloride ion and Sodium ion 。 If the ionic bond breaks, but no new bond is formed, the hydration caused by Nacl dissolving in water is not a chemical change, but only a physical change.

Most ions exist as hydrated ions in aqueous solutions.
