Talk:Aluminium sulfate

Wikipedia paid by aldrich and Fisher?

Dear Sirs,

a discussion about the commerciality of "Suppliers" is started here: http://en.wikipedia.org/wiki/User_talk:213.188.227.119

My main sorrow is, that these "suppliers" are in front of the literature and external links, making the commercial links seem to be more important than the scientific contents.

Medical Uses

If memory serves, Aluminium Sulphate is also used as a styptic (to check bleeding)... (AcrophobicEagle 06:51, 2 September 2005 (UTC))

Almost ten years later and this isn't included in the article ... why? To those editors who monitor and maintain this page, I strongly urge you to look into this. It is also the sole ingredient in "Stingose" by Johnson and Johnson Australia, I have no idea of it's efficacy, and frankly wouldn't be surprised if it's bunk as they also manufacture a lot of woo medications such as 'rubs' that allegedly assist in pain or injuries of muscles, etc. that just smell bad and burn your skin and have zero medical benefit.

Not so I have used Stingoes with great success in Western Austalia where l go every year to see my dsughter .It helps stop itching when bitten by mosquitoes.

Just this morning, my dentist used what he called "Alum Powder" to close up blood vessels in my gums to stop bleeding while creating and attaching a crown to my #19 molar. It seems use in Medical should include this use. Jmsmcfrlnd (talk) 17:26, 8 April 2019 (UTC)

Hydration

There is an inconsistancy in the article over the number of water molecules in the hydrate, either sixteen or eighteen. I will try to resolve this as soon as I can, and any input from other editors is welcome! Physchim62 08:23, 29 September 2005 (UTC)

• The hexadecahydrate (16H2O) is the varient sold by Sigma-Aldrich Co., and the one to which the CAS number in the table refers. I have changed the preparation section accordingly. Physchim62 06:24, 30 September 2005 (UTC)
• My sources show a variety of hydrates... General Chemical supplies a commercial 14H2O version and the current Fisher Scientific catalog indicates that their hydrate has "nH2O n=approx. 12-14". Two of my books, Standard Methods (in section 4500-NO3-D) and Water Quality, both refer to the 18H2O hydrate which is where I was originally looking. Perhaps it's best if we just say that there are a variety of hydrates ranging from 12 to 18? Musser 18:03, 5 October 2005 (UTC)

(can't find the ISBN for 12th edition). I have made a note that both hydrates are commonly found. --Ben Best 21:54, 15 November 2007 (UTC)

CAS number

Please check compound's CAS number. Its international chemical safety card says the number would be 10043-01-3 but referring the article the number would be 11828-11-8. Please check out which of them is correct and edit the article if needed. -Anzee 19:27, 30 November 2006 (UTC)

Molecular mass also seems to be incorrect. -Anzee 19:30, 30 November 2006 (UTC)

Looking into it.

You are right, 11828-11-8 does not exist, 10043-01-3 is aluminum sulfate 18-hydrate. I'll make some changes --Dirk Beetstra ^{T C} 19:36, 30 November 2006 (UTC)

how sulphoric acid react with aluminium oxide —Preceding unsigned comment added by 41.178.174.75 (talk) 21:13, 27 March 2009 (UTC)

Pentahydrate or heptadecahydrate?

I realised that the formula for the heptadecahydrate was ...5H₂O. Shouldn't that be pentahydrate? Also, the article went on to state that the 17-hydrate occured naturally as the mineral alunogen, which, according to its article, has the formula ...17H₂O, not ...5H₂O. Is anything wrong here?

Empirical formula

"...or Al2O12S3" - is that needed? Has anyone ever used this notation for aluminium sulfate? Alecjw (talk) 22:40, 1 August 2009 (UTC)

Incorret misinformation

"Ahmed Ressam, the al-Qaeda Millenium Bomber, used aluminum sulfate as one of the components in the explosives that he prepared to bomb Los Angeles International Airport on New Year's Eve 1999/2000; the explosives could have produced a blast 40x greater than that of a devastating car bomb.[4][5]"

This is a complete misinterpretation of the articles, which only states that it was found in his car, NOT that it was a component of the bomb. The text makes it out to look like aluminium sulfate is a powerful explosive when infact, it is a completely non-explosive compound. It simply can't explode. -Removed 90.227.176.140 (talk) 20:09, 11 June 2010 (UTC)

Meaning of equation

Im not sure of what the following was supposed to mean:

"Aluminium 3 + 3 Na₂SO₄ + 6 CO₂

The carbon dioxide + 3 Na₂SO₄ + 6 CO₂"

Is it some kind of remains lost in a change of the paragraph?

Spelling

Is "aluminium" a British version of the correct spelling: Aluminum? It's repeated several times, and I would be loath to correct it if there is a faction of subversive Anglophiles here co-opting the chemistry pages...Carl Jansen, jansenart.com

"Aluminium" is the preferred spelling of this element throughout Wikipedia's chemistry articles. See WP:ALUM for details. -- Ed (Edgar181) 22:03, 12 January 2011 (UTC)

Funnily enough it also uses the sulfate spelling instead of sulphate. Pleasetry (talk) 21:43, 2 October 2012 (UTC)

Which is the preferred spelling of that element. Win some, lose some, dependent upon your side of the pond.JSR (talk) 21:54, 2 October 2012 (UTC)

Aluminum sulfate in medical cream

Aluminum sulfate is listed as the second inactive ingredient in signature care hydrocortisone cream (store brand). It would be helpful to add this to the use section. https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=c6b9c4e1-bab8-490d-8c00-c43377ad0857 Lena Key (talk) 15:05, 25 March 2017 (UTC)
