Hazard Predictions

• Flammable: Reaction products may be flammable
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)

Solutions of alkali metals in liquid ammonia are powerful reducing agents ("solvated electrons") that slowly decompose to form hydrogen gas and strongly basic amide salts, which precipitate out of solution. Sodium amide can also be formed by the reaction of sodium metal with ammonia vapor (Eggeman, T. 2007. Sodium and Sodium Alloys. Kirk-Othmer Encyclopedia of Chemical Technology. (Online); Lange, L. and Triebel, W. 2000. Sodium Amide. Ullmann's Encyclopedia of Industrial Chemistry. (Online); Dickinson, F. 1961.
