I made a sizable batch of this a couple years ago, about a tablespoons worth, and I was sure it was still wet enough to work with wrong! Nitro compounds are explosive because although the diatomic form of nitrogen is very stable - that is, the triple bond that holds N2 together is very strong, and therefore has a great deal of bond energy - the nitro compounds themselves are unstable, as the bonds between nitrogen atoms and other atoms in nitro compounds are weak by comparison.

However, using the following method, a small quantity of dry NI3(s) crystals can be used to produce an impressive 'crack' and a beautiful cloud of purple iodine vapour mixed with nitrogen gas. Just a slight sting and loud noise. All parts of the preparation must be done in a fume cupboard and you must wear a face shield and gloves. It blew up while i was washing it down in the filter paper. (NH3)n] where n is 1 or 3. For some chemical compounds, triiodide indicates a salt of the named cation with the triiodide anion. The instability is also due to the combination of a large anion and a small cation. toxic fumes emitted sent firefighters to the hospital. chemistry. Rinse thoroughly. ; Brodie, B.B. Potassium iodide is a salt made up of the minerals potassium (K) and iodine (I). [10] It is most widely used in bang snaps. hydroxide; lead nitrate, 85% hydrazine hydrate; butyl nitrite or isopropyl - Nilay Ghosh. This problem has been solved! But I doubt it. All of these recipes have varying degrees of risk during production of explosives or fires because of improper use of chemicals. Potassium triiodide . "An explosive is any chemical compound or mechanical mixture that, when subjected to heat, impact, friction, detonation, or other suitable initiation, undergoes rapid chemical change, evolving large volumes of . Language links are at the top of the page across from the title. I wasnt injured, however my hand was purple and I needed clean underwear. Great fun we were banned from the boring services for years. and combustibles have a 1 to 4 rating in the red diamond (4 being the most highly The Stack Exchange reputation system: What's working? Nitric acid from a car battery? nitrate-fuel oil (ANFO) mixtures are a favorite of car and truck bombers. Cops, By. The dry papers will explode on contact. Sulfur; chlorine (generated from bleach or swimming To destroy any residual explosive on the glass rod or in the beaker, add 5 M NaOH solution (caution:corrosive) and leave until no black solid is visible. Note that there is an increase in the number of moles (4 versus 2), which means that the reaction is favored by entropy, because there are more possible microstates. What's the point of issuing an arrest warrant for Putin given that the chances of him getting arrested are effectively zero? If you're going to make take the right safety precautions. Being crowded around one end causes something called bond strain as the atoms repel each other in a small space.

How do you handle giving an invited university talk in a smaller room compared to previous speakers? friction, pressure, sound, light). are not. Other To make the solution, iodide crystals are crushed in a beaker and ammonia is poured over them. The three huge iodine atoms try to attach themselves to one small nitrogen ion, which means that the atoms are holding on to each other through a very weak bond. The The reaction between I2 and I- is an equilibrium. Detailed recipes for making these explosives may The triiodide ions are reduced back to iodide by thiosulfate at a much faster rate, until the thiosulfate is consumed. Caption. The triiodide .
