YOU WILL NEED:-
|
||
|
|
|
||
|
|
Iodine crystals (there is no substitute). Available from university
|
||
|
|
stockrooms (with a little pleading), VW&R, American Scientific and some drug
|
||
|
|
stores.
|
||
|
|
|
||
|
|
Ammonia (clear - not the detergent kind). Available in super-markets, drug
|
||
|
|
stores, hardware stores, and laboratory supply houses as above.
|
||
|
|
|
||
|
|
Heavy walled glass bottle with water tight lid. (Plastic lid - not metal.)
|
||
|
|
|
||
|
|
Strips of filter paper, newspaper or paper towel.
|
||
|
|
|
||
|
|
CHEMISTRY:-
|
||
|
|
|
||
|
|
3 I2 + 4 NH3 --------------> NI3 + 3 NH4I
|
||
|
|
|
||
|
|
iodine ammonia nitrogen ammonium
|
||
|
|
(crystals) (aqueous) tri- iodide
|
||
|
|
iodide
|
||
|
|
THE SETUP:-
|
||
|
|
|
||
|
|
Use about a teaspoonfull of iodine for a cup of laboratory grade ammonia, or
|
||
|
|
for about three cups of household ammonia. Put them in the bottle and put on the
|
||
|
|
lid, tightly. (Ammonia is easier to handle out of doors, or anywhere that is
|
||
|
|
well ventilated.) Swirl the bottle a bit, and let it stand over night.
|
||
|
|
|
||
|
|
USING IT:-
|
||
|
|
|
||
|
|
Select a non-metallic location where you want to use the NI3. It can be put
|
||
|
|
out either by scooping out some of the solid material from the bottom of the
|
||
|
|
bottle with a piece of paper, and leave the paper and the NI3 to dry. Alternatively
|
||
|
|
it can be scooped out with a plastic spoon (or a popsicle stick) or knife etc.,
|
||
|
|
and applied like frosting to places where people may walk, to banisters on
|
||
|
|
stairways or the underside of door-knobs. Pick a place where it will not be disturbed
|
||
|
|
until it is completely dry. The most important limitation is that it is
|
||
|
|
incompatible with metals, which will absorb the iodine out of the NI3 and turn to
|
||
|
|
rust.
|
||
|
|
|
||
|
|
The other thing to remember is NITROGEN TRI-IODIDE CANNOT BE MOVED AFTER IT IS
|
||
|
|
DRY. THE LEAST DISTURBANCE WILL SET IT OFF. If you put a piece of paper
|
||
|
|
smeared with it out in the sun to dry, or under a heat radiator in a room, the com-
|
||
|
|
bination of heat and the twisting of the paper as it drys, will make it hop a-
|
||
|
|
round at 1/2 to 5 minute intervals as areas of the prepared paper dry out.
|
||
|
|
Each hop is accompanied by a loud pop or snap, and if the location is obscure
|
||
|
|
enough, the comparatively long delay between pops can make it very hard to
|
||
|
|
find where the sound is coming from. If the NI3 is left in a cool dry place to dry
|
||
|
|
out, it will remain ready until it is touched, like a hand reaching for a
|
||
|
|
doorknob or sliding town a banister. Alternatively, NI3 can be applied to the
|
||
|
|
ground as a perimeter alarm, because no matter how gently or quietly it it
|
||
|
|
stepped on, it's gonna go BANG!
