Miscellaneous discussion[edit]

According to Sulfur, the IUPAC accepted spelling of sulfur should be with an 'f' and not 'ph'. As this is the convention then it should be followed in this article. --Artorius 13:22, 15 Jun 2005 (UTC)

In BE, it is spelt Sulphur. Kilo-Lima 14:45, 30 September 2005 (UTC)


I'm reading-and-wikifying Trent's Last Case for Wikisource right now, and have come across one part in which Trent refers in a photographical context to "hypo-eliminator."

'That is called hypo-eliminator,' said Trent, as Mr Cupples uncorked and smelt at one of the bottles. 'Very useful when you're in a hurry with a negative. I shouldn't drink it, though, all the same. It eliminates sodium hypophosphite, but I shouldn't wonder if it would eliminate human beings too.'

I gather that this is likely not sodium thiosulfate, but something else entirely. Does anyone versed in photography circa 1913 have any idea what it might be? --Quuxplusone 17:24, 19 July 2005 (UTC)

"Hypo" is Ammonium Thiosulfate. (talk) 20:45, 1 February 2012 (UTC)

Chlorine eliminator[edit]

How about mentioning sodium thiosulfate's use for removing chlorine from water, important for those keeping fish in aquariums (and how this works). Gary 11:49, 9 April 2006 (UTC) hfshfshfsfhsfj vf — Preceding unsigned comment added by (talk) 14:47, 8 November 2012 (UTC)

Safety of sodium thiosulfate in swimming pools; signs & symptoms of overuse[edit]

My son is a member of the high school swim team. The school uses this product in the pool. This year, many members of the team have experienced thinning hair with loss of hair color, loss of hair to body, red, dry skin, respiratory illness and asthma-like symptoms, nausea, gastric reflux and malaise. Any comments? Info? Thank you for your input. —The preceding unsigned comment was added by (talk) 03:20, 29 January 2007 (UTC).

Sounds nasty, but no need to shout it. Do you have reason to associate the symptoms with the chemical? Dicklyon 03:37, 29 January 2007 (UTC)

More info forth coming[edit]

I intend on adding the reactions of Sodium thiosulfate can be used to determine oxygen content of water. It has to do with iodine.LoyalSoldier 06:17, 23 March 2007 (UTC)


Are there any safety precautions required when handling Sodium Thiosulphate?

In principal it is more untoxic than table salt. It has therefore only few general precautions. The R-Phrase 35 which is mentioned is wrong. It has no R-Phrase. — Preceding unsigned comment added by (talk) 15:26, 23 November 2015 (UTC)

link from Na2S2O3[edit]

shouldn't a search for Na2S2O3 redirect to this page? —Preceding unsigned comment added by Speaker4thadead (talkcontribs) 02:04, 15 September 2008 (UTC)

Done. You can do it yourself too! See WP:REDIRECT for the instructions. --Itub (talk) 17:06, 15 September 2008 (UTC)

solubility in water[edit]

the solubility given here as 20.9 g/100 ml at 20 °C is in error and far less than that given in other sources, including the wikipedia article "solubility table," which gives it as 73 g/100 g water at 20 °C. AND, why is the solubility given per volume of water anyway? It should be in grams of water, since that is the standard because H2O volume changes with temperature. — Preceding unsigned comment added by Zomax7000 (talkcontribs) 10:59, 19 May 2010
