Symbol N. Atomic weight 14.007. It was formerly regarded as a permanent noncondensible gas, but was liquefied in 1877 by Cailletet of Paris, and Pictet of Geneva, and boils at -195.8 / C at atmospheric pressure.

Pertaining to, derived from, or designating, a complex acid called nitroprussic acid, obtained indirectly by the action of nitric acid on potassium ferrocyanide (yellow prussiate), as a red crystalline unstable substance. It forms salts called nitroprussides, which give a rich purple color with alkaline sulphides.

See Nitroprussic.
