Properties: Faintly yellow, monoclinic crystals from water. d 1.906. Melts with decompn forming an olive-green mass. Freely sol in water, acetic acid solns. Insol in alcohol. Very slightly sol in liq ammonia. Dec by strong mineral acids. Aq solns are slightly yellow and are regarded as non-poisonous when freshly prepd: Zwenger, Ann.
62, 178 (1847). An odor of HCN develops after about one week's standing in the dark. Exposure to light causes rapid development of a yellow color, but hydrolysis is slight.
