In some contexts, water of crystallization is the total mass of water in a substance at a given temperature and is mostly present in a definite (stoichiometric) ratio. Classically, "water of crystallization" refers to water that is found in the crystalline framework of a metal complex or a salt, which is not directly bonded to the metal cation.
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 ).
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 ...
Consider the average number of particles with particle properties denoted by a particle state vector (x,r) (where x corresponds to particle properties like size, density, etc. also known as internal coordinates and, r corresponds to spatial position or external coordinates) dispersed in a continuous phase defined by a phase vector Y(r,t) (which again is a function of all such vectors which ...
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 ...
Zinc sulfate is an inorganic compound with the formula ZnSO 4.It forms hydrates ZnSO 4 ·nH 2 O, where n can range from 0 to 7. All are colorless solids. The most common form includes water of crystallization as the heptahydrate, [4] with the formula Zn SO 4 ·7H 2 O.

It is one of the few salts whose solubility in water decreases with rising temperature. [1] Cerium(III) sulfate is a hygroscopic white solid, which begins to decompose above 600°C. It has a monoclinic crystal structure. Cerium(III) sulfate tetrahydrate is a white solid that releases its water of crystallisation at 220 °C.
