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.
