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