Talk:Sodium bisulfite

message: In  the introduction, this article states "Sodium bisulfite in contact with chlorine bleach (aqueous solution of sodium hypochlorite) will release harmful fumes."  I cannot seem to find a source for this anywhere and would at least like an explanation of WHAT gas it is (these are after all fairly simple molecules and the only thing i can think it could be is Cl2.)  —Preceding unsigned comment added by Brvman (talk • contribs) 01:41, 20 October 2010 (UTC)

message: I added a section on bisulfite sequencing, a common technique used when analyzing the methylation status of DNA, which is related to the epigenetic regulation of gene expression.
If anyone has a good image exemplifying the technique, it might be nice to add it. Mjatucla 02:58, 13 December 2006 (UTC)

message: It would be very nice to have comparative chart of antioxidant capacity of Sulfites, Bi-sulfites & metabisulfites, if anyone has done so by experimentation?  —Preceding unsigned comment added by 125.16.17.1 (talk) 04:13, 28 December 2007 (UTC)

message: This article's infobox currently states NaHSO3 is a white solid with a density of 1.48 g/cm3, a melting point of 150 °C and a refractive index of 1.526. Yet according to an article in J. Chem. Educ., NaHSO3 does not exist as a solid. Concentrated solutions of Na+ and HSO3− evaporate to yield sodium metabisulfite, Na2S2O5 instead. Greenwood & Earnshaw says much the same thing in more general terms: "attempts to isolate MIHSO3 tend to produce disulfites by "dehydration": 2HSO3−  S2O52− + H2O". I will correct the article soon unless anyone objects.

message: The paragraph under "Industrial uses" about steam boilers is mostly copy-pasted from the cited source. I don't know how to evaluate the source's reliability or care enough to rewrite it myself. Cheers.Junkyardprince (talk) 03:14, 10 October 2017 (UTC)
