Ammonium thioglycolate 

Hi,
Following up on a request, I did a rewrite on ammonium thioglycolate.  However I question the chemistry, of the thioglycolic acid transferring a hydrogen onto sulfur to break the S-S bond; rather, I suspect that the thiol group is involved.  Do you have a reference for this information? I added a "disputed" tag to the article, but I would like to remove that ASAP after settling the issue one way or the other.  Cheers,
