Talk:Phosphite anion

message: I always hear about phosphorous in relationship to water pollution.  Could somebody write about this substances role in water pollution and it's environmental impact?
:You probably mean phosphates. There is a big difference between phosphorus (P), phosphorous (HPO32-), and phosphate (PO43-).
:See phosphate and eutrophication for the details, but in a nutshell, algae consume phosphates and oxygen to produce energy. If large amounts of phosphates are introduced into a body of water, the algae population increases exponentially and rapidly consumes the oxygen dissolved in the water. When this happens, every organism that depends on dissolved oxygen dies out and the lake loses its ability to sustain life.

::As the phosphite article mentions briefly, salts of phosphorous acid are being considered for fertilizers, apparently because they are more soluble than, say, ammonium phosphate.--Smokefoot 22:23, 13 February 2006 (UTC)
replies: text: I agree, the dianion is initially a little surprising to many, but check a first-year chem book, and if that does not work, read further - say Greenwood and Earnshaw, which underpins a lot of the inorganic pages.--Smokefoot 12:48, 18 August 2006 (UTC)
thread_title: Question

message: The naming of phosphorus oxoanions  (oxyanions historically) and acids is a mess. While we might not like it the ion is HPO32− not PO33-. I am not even sure if the PO33- ion is known. The more rational naming of IUPAC will probably never be adopted- so we just have to live with the confusing naming we have inherited from our predecessors. I guess the confusion is "compounded" by the naming of P(OR)3 as  phosphites. --Axiosaurus (talk) 18:13, 23 November 2008 (UTC)
replies: text: As a by the by- just to add to the confusion - IUPAC actually would name the PO33− ion phosphite and HPO32− phosphonate- as they recommend the name phosphonic acid for HPO(OH)2.--Axiosaurus (talk) 11:29, 24 November 2008 (UTC)
replies: text:  This article is about phosphonate... my chemistry class teaches that the Phosphite ion is PO33-. JudelFoir (talk) 23:07, 29 October 2009 (UTC)

thread_title:  As life's first energy source 

message: I have introduced some cautions in the main phosphite article section on Plant Use, because I was unable to find the one cited source in my local library, and several of the statements appear ambiguous or dubious.  Inorganic phosphATES are well known fertilizers, and organophoshATE   esters are well known insecticides, but I was unable to find any online sources for phosphITES (inorganic or organic) as either fertilizers or fungicides.  Could someone with more expertise or agricultural library access please help clarify this section? CharlesHBennett (talk) 20:09, 6 December 2010 (UTC)
thread_title:  Phosphite fertilizer/pesticide? 

message: I have removed some incorrect references- Loubs work was not about salts of PO33- ion but about salts containing HPO32- and  H2PO3-  so there is no evidence for the structure of the elusive PO33- ion. Greenwood does not mention this ion at all so I have removed the reference supporting the oxidation state of +3. Axiosaurus (talk) 16:59, 19 December 2012 (UTC)
thread_title:  Changes to lede 

message: i have rewritten some of this to try to help resolve the confusion caused by the conflict between the IUPAC name phosphite, which is now being more widely used and the legacy use of the name which still continues particularly in agrichemicals field. I believe that UK A level refers to HPO32- as phosphite but I haven't got a reference for that. I have also added a brief comparison to arsenite and sulfite and  a structure picture of HPO32- courtesy of Ben. The user box is mess. I cannot find a reliable CAS# for either the IUPAC phosphite or the legacy phosphite ions

message: The image is one of the phosphite ester rather than the IUPAC phosphite PO33- (non existant) ion or the real HPO32- (IUPAC phosphonate) ion often called phosphite. Is the image appropriate.Axiosaurus (talk) 07:56, 23 June 2014 (UTC)
replies: text: As described in Phosphite.  --Smokefoot (talk) 12:41, 23 June 2014 (UTC)
replies: text: If someone removes the image, I suggest you leave behind a comment in there. Since it's eponymous, another GF editor might come along and add it, like I did. -DePiep (talk) 15:27, 23 June 2014 (UTC)

message: "Salts containing 
 cannot be isolated from aqueous solutions of phosphorous acid. Only salts containing  or  are produced. There are reports of a salt Na3PO3 in older literatureModern Inorganic Chemistry, Joseph Mellor, Longmans, Green and Company, 1917 and the use of sodium metal to remove the third hydrogen in H3PO3 is mentioned in a textbook. However, if  is produced in aqueous solution or dissolved it would form  or  immediately.  Na3PO3 is referred to in many textbooks on Internet sources, often as part of an exercise in naming inorganic compounds, but also as a misprint of the formula for the phosphate salt, Na3PO4."
seemed like negative info, so I took it out. --Smokefoot (talk) 23:05, 6 July 2017 (UTC)
