  2. Water of crystallization - Wikipedia

    en.wikipedia.org/wiki/Water_of_crystallization

    Water of crystallization can generally be removed by heating a sample but the crystalline properties are often lost. Compared to inorganic salts, proteins crystallize with large amounts of water in the crystal lattice. A water content of 50% is not uncommon for proteins.

  3. Hydration isomerism - Wikipedia

    en.wikipedia.org/wiki/Hydration_isomerism

    One example is the pair [CrCl(H 2 O) 5]Cl 2 •H 2 O and [Cr(H 2 O) 6]Cl 3. [1] The former has one water of crystallization but the latter does not. Another example is the pair of titanium(III) chlorides, [Ti(H 2 O) 6]Cl 3 and [Ti(H 2 O) 4 Cl 2]Cl(H 2 O) 2. The former is violet and the latter, with two molecules of water of crystallization, is ...

  4. Hydrate - Wikipedia

    en.wikipedia.org/wiki/Hydrate

    Another example is chloral hydrate, CCl 3 −CH(OH) 2, which can be formed by reaction of water with chloral, CCl 3 −CH=O. Many organic molecules, as well as inorganic molecules, form crystals that incorporate water into the crystalline structure without chemical alteration of the organic molecule (water of crystallization).

  5. Crystallization - Wikipedia

    en.wikipedia.org/wiki/Crystallization

    An example of this crystallization process is the production of ... for example, the mass of water of hydration to reach a stable hydrate crystallization form is ...

  6. Mineral hydration - Wikipedia

    en.wikipedia.org/wiki/Mineral_hydration

    Some mineral structures, for example, montmorillonite, are capable of including a variable amount of water without significant change to the mineral structure. [citation needed] Hydration is the mechanism by which hydraulic binders such as Portland cement develop strength. A hydraulic binder is a material that can set and harden submerged in ...

  7. Efflorescence - Wikipedia

    en.wikipedia.org/wiki/Efflorescence

    Copper(II) sulfate (bluestone) (CuSO 4.5H 2 O) is a blue crystalline solid that when exposed to air, slowly loses water of crystallization from its surface to form a white layer of anhydrous copper(II) sulfate. Sodium carbonate decahydrate (Na 2 CO 3.10H 2 O) will lose water when exposed to air.

  8. Transition metal chloride complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_chloride...

    "Nickel dichloride hexahydrate" consists of the chloride complex trans-[NiCl 2 (H 2 O) 4 plus water of crystallization. As indicated in the table below, many hydrates of metal chlorides are molecular complexes. [78] [79] These compounds are often important commercial sources of transition metal chlorides. Several hydrated metal chlorides are ...

  9. Sodium carbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_carbonate

    Sodium carbonate decahydrate (Na 2 CO 3 ·10H 2 O), also known as washing soda, is the most common hydrate of sodium carbonate containing 10 molecules of water of crystallization. Soda ash is dissolved in water and crystallized to get washing soda. +
