Summary

Description
Demonstration of the explosive properties of three different explosives. An explosive is set on a solid marble base and is initiated by glowing wooden stick. The intensity of detonation and appearance of flame is different in each case.
  1. Explosion of silver carbide (silver acetylide), Ag2C2. This is unstable compound that decomposes under heat or impact. Characteristic for this explosive is that when detonated, no gaseous products are liberated: Ag2C2(s) = 2Ag(s) + 2C(s). The explosion is accompanied by very short flash.
  2. Explosion of mercury(II) fulminate Hg(CNO)2. This explosive is thermal and sensitive to impact. When exploded, it decomposes to elemental mercury, carbon and gases (CO2 and N2).
  3. Combustion of peroxyacetone (acetone peroxide), C6H12O4 (cyclic dimer) or C9H18O6 (cyclic trimer). Even though peroxiacetone is explosive substance, it burns quite still when initiated by glowing wooden stick. It is characteristic that this explosive burns without a solid residual.
Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.
