water of hydration

When you add a salt, a competition for water of hydration is set up.

Its blue color is due to water of hydration.

The water of hydration can be removed in vacuo.

K ions must give up their water of hydration to pass through the pore.

Hydration reactions are all reversed by heating to drive off the water of hydration.

Water of hydration abounded in the minerals.

Such hydrates are also said to contain water of crystallization or water of hydration.

Others trap water as water of hydration in their crystalline structure, such as sodium sulfate.

When FeO HO is heated, it loses its water of hydration.

However, the term is also applied to an equimolar mixture of those two salts, with whatever water of hydration the sodium carbonate includes, supplied as a powder.

In the TGA trace of calcium oxalate monohydrate, the first mass loss corresponds to loss of water of hydration.

In crystallography, water of crystallization or water of hydration or crystallization water is water that occurs inside crystals.

The product is hydrated and the formula is sometimes written MgO:XSiO-HO to show the water of hydration.

The crystal structure was later resolved by Peterson and Wang in 2006, revealing it belonged to the triclinic crystal system, and possessed 11 waters of hydration, not 12.

Hydrates of crystals often form at different temperatures, so mass due to water of hydration of the crystals can cause a difference in mass, as well as rate of crystalization.

Hydrates form with the formula NaSiO-nHO which contain the discrete, approximately tetrahedral anion SiO(OH) with waters of hydration.

Vince Calder Because the NaOH and KOH are deliquescent and/or may have water of hydration in them, these solids are usually considered not good for accurate titrations.

The dogma of ion transport states that the transporter recognises the ion then progressively removes the water of hydration, removing most or all of the water at a selective pore before releasing the ion on the far side of the membrane.

Pure pHEMA yields lenses that are too thick for sufficient oxygen to diffuse through, so all contact lenses that are pHEMA based are manufactured with copolymers that make the gel thinner and increase its water of hydration.

In addition, the discovery of water of hydration band on 773 Irmintraud meant that there may be major differences in mineralogy within individual type classification and astronomers must be careful in assuming that the C-, D-, and other type classification relate directly to mineralogy.

However, in analyzing the spectra of 773 Irmintraud for the water of hydration band (the 3- m absorption feature of hydrated silicates), Lebofsky discovered the first D-type asteroid to show the water of hydration band on the surface of the asteroid.
