Would whoever posted this notice please indicate what drawing exactly is requested and why? There are many possible structures and reactions which could be illustrated.Dirac66 01:51, 29 October 2007 (UTC)

After writing the above I checked the history and found that the notice was posted by a bot, whose owner has since informed me that the posting is based on this discussion, based on the suggestion that EVERY article in the category Chemical Compounds needs a picture.

So do the editors of this article feel it needs a picture? If so, my suggestion would be the anhydrous (blue) and hydrated (pink) forms of Cobalt (II) chloride, which are used to detect moisture. Would anyone like to copy the images from the CoCl₂ article to this article? Are there other suggestions? Dirac66 02:33, 30 October 2007 (UTC)

[edit] Opposite of hydrate

"The opposite of a hydrate is an anhydrate, such substances contain no water or form no water upon heating." I am pritty sure they can from water from heating but, but the prosses is ireversible, for instance when sucrose caramleizes.

I have now rewritten this sentence to include the possibility of loss of further water upon strong heating. Dirac66 19:49, 28 October 2007 (UTC)

In computer science, hydrate is analogous to deserialization, the opposite of which is serialization. —Preceding unsigned comment added by 64.128.15.226 (talk) 22:14, 11 April 2008 (UTC)

[edit] Recent Edit For Fire Protection and Construction Issues

As far as the removal of the reference box: I also did not see a book or a website reference, but this is pretty basic chemistry. The references to construction, passive fire protection, refractories, such as sodium silicate and space physics are all internal to Wikipedia by now. As far as the hydration energy, there is more than one way to look at that. If you look at the topic of heat of hydration in cement chemistry, as well as the energy it takes to liberate hydrates, which thus takes energy photons away from the fire or the heat that is experienced during atmosspheric re-entry, it will shed light on the subject matter.--Achim 22:29, 4 May 2006 (UTC)

I'm very unclear about the appropriateness of substances such as Ethanol as a hydrate in the sense that the water can be eliminated. Clearly Ethanol is usually found bound with water (cf. anhydrous alcohol) which can be eliminated to a degree by distallation --- but the substance itself I'm not so sure. Now I understand that Ethyl Hydrate is sometimes used as synonym to Ethanol but I think the distinction should be made more clearly - what do others think? The same surely applies to hydroxide. Water cannot be removed from a hydroxide - any more than an oxide or a carbonate (except of course where there is molecular water integrated into the crystal structure).

Am I correct in assuming that hydration energy is the enrgy in Hydrates? Or merely the energy in water? Bug 09:18, 16 December 2005 (UTC)

[edit] Refractories?

Or perhaps factories? OlavN 07:21, 6 July 2007 (UTC)
