- Chloramine, NH2Cl is most easily formed by mixing chlorine bleach
- (liquid original Chlorox tm) with ammonium chloride. The bubbles that
- form are chloramine, and they do explode. Chloramine is also formed in
- swimming pools when sweat and (ugh) urine react with the chlorine bleach
- used to treat the water. If you find certain pools irritating to the
- eyes and nose, bear in mind that the chloramine you are making by the
- above process is about 1000 times more concentrated. It is EXTREMELY
- dangerous to breath.
-
- You can do the experiment outside in a wax paper cup. Pout the NH4Cl
- (about 1/4 teaspoon) into the bleach solution. Light the bubbles with a
- match by throwing same, not by holding same, in the cup. A loud POP
- results.
-
- NCl3 can be formed by mixing NH4Cl with HCl solution and then adding
- bleach slowly while cooling the mixture in an ice bath. It's the
- equivalent of bubbling Cl2 through the NH4 salt. THIS HAS A NASTY HABIT
- OF EXPLODING AND KILLING THE PEOPLE WHO TRY IT THOUGH.
-
- Neither NH2Cl nor NCl3 is as unstable as NI3 but then, what is? I
- certainly would never complain about the stubborn stability of NCl3.

- Sometimes I think this group doesn't need an FAQ list. Sometimes I think
- this group IS an FAQ list.
