Explosive silver in an explosive
Explosive silver in an explosive new video!
Reagents and equipment: calcium carbide, 50mL Tollens’ reagent, water, conical flasks, cork with gas pipe, funnel, filter paper, burner.
Add a small piece of calcium carbide to a conical flask with 50mL of water, and close it using a cork with a gas outlet tube. Immerse the free end of the gas outlet tube in 50mL of Tollens’ reagent. Wait for the reaction to die down. A loose, greyish-white precipitate will form in the second flask. Filter it through a funnel with filter paper and rinse with water. Pat the precipitate dry with filter paper and set a small amount on fire. And boom!
The reaction between calcium carbide and water produces acetylene gas and calcium hydroxide: CaC2+2H2O→Ca(OH)2+C2H2↑ Passing acetylene gas through a solution of Tollens’ reagent (ammonia silver hydroxide solution) yields a friable grey-white precipitate of silver acetylide: C2H2+2[Ag(NH3)2]OH→Ag2C2↓+4NH3↑+2H2O
Silver acetylide is an extremely unstable explosive. The fewer impurities it contains, the more dangerous it is. Silver acetylide can explode when heated and mechanically stressed.
Ag2C2(solid)→2Ag(solid)+2C(solid)
Safety precautions: Do not try this at home. Only under professional supervision.
