  2. Hydration reaction - Wikipedia

    en.wikipedia.org/wiki/Hydration_reaction

    In chemistry, a hydration reaction is a chemical reaction in which a substance combines with water. In organic chemistry, water is added to an unsaturated substrate, which is usually an alkene or an alkyne. This type of reaction is employed industrially to produce ethanol, isopropanol, and butan-2-ol. [1]

  3. Hydration energy - Wikipedia

    en.wikipedia.org/wiki/Hydration_energy

    In chemistry, hydration energy (also hydration enthalpy) is the amount of energy released when one mole of ions undergoes solvation. Hydration energy is one component in the quantitative analysis of solvation. It is a particular special case of water. [1] The value of hydration energies is one of the most challenging aspects of structural ...

  4. Hydrate - Wikipedia

    en.wikipedia.org/wiki/Hydrate

    In organic chemistry, a hydrate is a compound formed by the hydration, i.e. "Addition of water or of the elements of water (i.e. H and OH) to a molecular entity". [5] For example: ethanol , CH 3 −CH 2 −OH , is the product of the hydration reaction of ethene , CH 2 =CH 2 , formed by the addition of H to one C and OH to the other C, and so ...

  5. Solvation shell - Wikipedia

    en.wikipedia.org/wiki/Solvation_shell

    The number of solvent molecules surrounding each unit of solute is called the hydration number of the solute. A classic example is when water molecules arrange around a metal ion. If the metal ion is a cation, the electronegative oxygen atom of the water molecule would be attracted electrostatically to the positive charge on the metal ion.

  6. Dehydration reaction - Wikipedia

    en.wikipedia.org/wiki/Dehydration_reaction

    In chemistry, a dehydration reaction is a chemical reaction that involves the loss of water from the reacting molecule or ion. Dehydration reactions are common processes, the reverse of a hydration reaction .

  9. Hydration number - Wikipedia

    en.wikipedia.org/wiki/Hydration_number

    The hydration number of a compound is defined as the number of molecules of water bonded to a central ion, often a metal cation. The hydration number is related to the broader concept of solvation number, the number of solvent molecules bonded to a central atom. The hydration number varies with the atom or ion of interest.
