A quote from http://www.ilpi.com/msds/ref/amine.html :
"Mixing household ammonia and chlorine bleach is exceedingly dangerous and produces a toxic and carcinogenic mixture of chloramine, NH2Cl, and
hydrazine, N2H4 (not, as many believe, chlorine gas, Cl2)."
I was one of the many, who always thought that it was chlorine gas...something like 2NaOCl + 2NH3 --> 2NaONH3 + Cl2 (dunno what the name for the
ONH3- ion is either...)
What reactions actually happen to give hydrazine and chloramine, and are they produced simultaneously or does it depend on intial concentration?

Chlorine is produced when acid and bleach are mixed, not ammonia and bleach.
Hydrazine has beem discussed here:
http://www.sciencemadness.org/talk/viewthread.php?tid=1128
And Here
http://www.sciencemadness.org/talk/viewthread.php?tid=757
Strangely enough, when I used the search feature of this site to search "hydrazine" to find Mr. Anonymous' method for hydrazine sulfate
it did not turn up. Despite the word hydrazine occuring many times in that thread. I was required to search for "Mr. Anonymous" to find
that thread. Weird.
Also, I was under the impression that hydrazine sulfate was really piosonous stuff. The MSDS list it as an anticipated carcinogen. But this place makes it seem beneficial to people. So which is it?

if your are talking about comet bleach
then it is:
Sodium dichloro-s-triazinetrione + Ammonium Hydroxide OR:
C3N3O3Cl2Na+ NHOH--> NH2Cl + N2H4
I think its something like that atleast.

i have got a certain idea that that the bleach in water varies between stages of sodium hydroxide and chlorine, and sodium hypochlorite. So, if you
were to add ammonium compounds to it, ammonia and chlorine would be produced, both of which will react to give varying products of hydrazine and
chloramine, as stated, since chlorine is a strong oxidising agent.
Correct me on this theory if it is dead wrong, its just an offhand idea..

I've posted a thread in forum matters to exactly prevent this kind of threads, yet some people apparently never learn.
Check the two other topics linked to and use either the forums search engine or google to search this site, like explained in THIS thread.
