Protein crystals commonly have as much as 50% water content. Molecules are also labeled as hydrates for historical reasons not covered above. Glucose, C 6 H 12 O 6, was originally thought of as C 6 (H 2 O) 6 and described as a carbohydrate. Hydrate formation is common for active ingredients. Many manufacturing processes provide an opportunity ...
Minerals that are chemical hydrates, including molecules of water in their crystal structure. Subcategories This category has the following 7 subcategories, out of 7 total.
γ-Cyclodextrin exists as a white (colorless) powder or crystals. The density of its hydrate crystal (γCD·14H 2 O) is 1.41 g/cm 3 . γ-Cyclodextrin is well soluble in water and dimethyl sulfoxide , poorly soluble in methanol .
There are two main ways in which minerals hydrate. One is conversion of an oxide to a double hydroxide , as with the hydration of calcium oxide —CaO—to calcium hydroxide —Ca(OH) 2 . The other is with the incorporation of water molecules directly into the crystalline structure of a new mineral, [ 1 ] as with the hydration of feldspars to ...
This category has the following 2 subcategories, out of 2 total. C. Clathrate hydrates ... Chloral hydrate; Cobalt(II) sulfate; F. Friedel's salt; G. Gas hydrate ...
This metal aquo complex crystallizes with water of hydration, which interacts with the sulfate and with the [Fe(H 2 O) 6] 2+ centers. A salt with associated water of crystallization is known as a hydrate. The structure of hydrates can be quite elaborate, because of the existence of hydrogen bonds that define polymeric structures.
Clathrate hydrate, which encaged CO 2 as guest molecule is termed as CO 2 hydrate. The term CO 2 hydrates are more commonly used these days with its relevance in anthropogenic CO 2 capture and sequestration. A nonstoichiometric compound, carbon dioxide hydrate, is composed of hydrogen-bonded water molecules arranged in ice-like frameworks that ...
Forms crystalline hydrates of the composition MnC 2 O 4 •n H 2 O, where n = 2 and 3. [6] Crystalline hydrate of the composition MnC 2 O 4 •2H 2 O forms light pink crystals of the orthorhombic system, space group P2 1 2 1 2 1, cell parameters a = 0.6262 nm, b = 1.3585 nm, c = 0.6091 nm, Z = 4, melts in its own crystallization water at 100°C ...
