Properties: Light yellow, odorless powder; slowly darkened by light. Crystals are hexagonal or cubic. d 5.67; mp 552°. Practically insol in water (0.03 mg/l); in acid (except concd HI in which it dissolves readily on heating); in ammonium carbonate. Freely sol in solns of alkali cyanides or iodides; 35 mg dissolve in a liter of 10% ammonia; appreciably sol in concd solns of alkali bromides, chlorides, thiocyanates, thiosulfates, mercuric and silver nitrates. It is slowly attacked by boiling concd acids, but not affected by hot solns of alkali hydroxides.
