[[Media:Example.ogg]]Is there any relationship (in general) between metal-water coordination complexes and water of crystalization? I know that the chemistry of coordination compounds cannot be simplied to be shown in a very general way, but if there is any relationship between coordination of the metal ion with the water of crystalization, it should be mentioned here. For intance, we can say that an alum crystal has 6 water molecules per each metal ion (either potassium or aluminium), could this imply that each one of these ions has 6 water molecules attached? --Paiconos 16:17, 20 September 2005 (UTC) copper sulfate pentahydrate is an example. —Preceding unsigned comment added by (talk) 15:16, 26 April 2008 (UTC)


when you heat sugar on the stove, you get a lot of water vapor and steam coming off... is this "water of crystallization"? — Preceding unsigned comment added by (talk) 22:43, 27 May 2012 (UTC)

Not really. The steam that you see arises (I am guessing) from the chemical degradation of sugar. The idea of the water of crystallization is water that kind of gets trapped in the crystal, not occluded like a bubble but fits in between molecules (or more commonly ions). Compounds that lose water of crystallization can be reconstituted whereas water evaporated in thermal chemical degradation is usually lost forever.--Smokefoot (talk) 22:51, 27 May 2012 (UTC)
