n 1: dryness resulting from the removal of water [syn: dehydration] 2: the process of extracting moisture (as by heat) [syn: dehydration, drying up, evaporation]

which is, literally, a dictionary definition.
Reinstated the comment about coconut from the mispelled version. If it's removed again, it's normal to add it to the talk page. Andrewa 17:31, 18 Mar 2004 (UTC)
article is mis-spelled
This is mis-spelled: should be desiccation etc. See for example http://www.merriam-webster.com/cgi-bin/dictionary?book=Dictionary&va=desiccation and http://www.hyperdictionary.com/dictionary/desiccation
OOPS. So it is. A very common mistake, and it will be a pain to fix here while preserving the histories. Mea culpa so I'll have a go. Andrewa 17:38, 13 Apr 2004 (UTC)
Ah me. Cut and pasted from the now-deleted original talk page from the correctly (as it turned out) spelled version:
Redirect to correct spelling needed as
2. History should be preserved. Of course it could be merged.

...just so it's clear I'm not covering my tracks. The only significant author whose history has been lost is me. I don't think that's a problem. Now to fix those 'corrections' I made before!!! Moral: Google is a lousy spell checker. Andrewa 18:05, 13 Apr 2004 (UTC)
I added a link to the Silica Gel Page (it has a LOT of information!) --fixman88 00:50, May 21, 2005 (UTC)
Hello, I got a question concerning drying agents. Which of the following is suitable for use in / as a desiccator?
Calcium hydride/Magnesium perchlorate/Magnesium sulphate/Lithium Aluminium Hydride
I suppose all of them can be used, so maybe which is the most suitable. --Cjingren 12:55, 27 July 2005 (UTC)
- LiAlH4? Nooooo way, especially not if my solvent is an alcohol. That would react with hydroxyls like nobody's business, being a most powerful reducing agent. Anhydrous magnesium sulfate would be the best be. GreatMizuti 09:59, 17 January 2007 (UTC)
Incorrect use of terms
"A desiccant is a substance that absorbs or adsorbs water."
absorbtion is where there is bonding between a substance and a fluid, adsorption occurs between a solid and another substance. It is my understanding that all desiccants are solids and therefore only adsorption occurs, not absorption.
Also this sentence is a bit confusing and requires clarification.
- Your understanding is perhaps a little weak but your premise is correct. A fluid is itself a substance that can indeed by absorbed by a solid (eg crystal structure of epsomite [] vs anhydrous magnesium sulfate )in the case of some dessicants there is actually a reaction between water and the dessicant in order to purge the system of water, so a dessicant need not absorb or adsorb water in order to serve its function.

Hey, I have to do a project on desiccation in plants for school. Does anyone know anything about how farmers use desiccation in their plants?
Complex vs Compound
When one is writing the formula for a complex the counter-ion isn't relevant, certainly in this case the counter-ion is in now way responsible for the colour that the complex appears to have. If you're writing the the formula for a co-ordination compound then certainly the counter-ion must be written.GreatMizuti 04:03, 28 October 2007 (UTC)
