[Untitled][edit]

Article moved from mispelled entry.

Removed text from this original entry:

dessication

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[edit]

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

1. It's quite a common misspelling, what links here includes Arthrobacter, Vacuum, Ichthyostega and Berber as I write. Of course these should be fixed, but they demonstrate how common it is.

2. History should be preserved. Of course it could be merged.

Misspellings above corrected, see [1], [2], [3], [4] for the misspelled versions. Andrewa 18:03, 18 Mar 2004 (UTC)

...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)

Added a link[edit]

I added a link to the Silica Gel Page (it has a LOT of information!) --fixman88 00:50, May 21, 2005 (UTC)

Desiccator Question[edit]

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)[reply]

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)[reply]

Commonly used is self-indicating silica gel. Take a look at the picture in desiccator. If you need it to be exceptionally dry, a desiccator may not be the best solution. Maybe a glove box. --Rifleman 82 10:48, 17 January 2007 (UTC)[reply]

Incorrect use of terms[edit]

"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.

Chris

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 [[5]] 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?

Thank you! 196.210.245.171 (talk) 18:58, 17 April 2012 (UTC)Cheri[reply]

Complex vs Compound[edit]

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)[reply]

Desert Desiccation[edit]

This is the term for the gradual growing of the Sahara and other deserts. ~ 71.109.149.49 (talk) 03:49, 29 October 2009 (UTC)[reply]
