Hazard Predictions

• Corrosive: Reaction products may be corrosive
• Explosive: Reaction products may be explosive or sensitive to shock or friction
• 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 calcium or magnesium metal in liquid ammonia act as powerful reducing agents ("solvated electrons") that slowly decompose to form hydrogen gas and strongly basic and explosive metal amide salts, which precipitate out of solution (E. M. Kaiser, Synthesis, 1972, (8), p. 391-415; W.C. Fernelius and G.W. Watt, Chem. Rev. 1937, 20, 195-258; Eggeman, T. 2001. Ammonia. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).
