Apr 01, 2021 In the absence of ferric oxide, sodium cyanide decomposes at 587.4 C in air and 879.2 C in argon atmosphere. In the presence of ferric oxide, about 60% of sodium cyanide decomposes at 350 C for 30 min in argon, while almost all sodium cyanide decomposes within 30 min in air or O2 with mass ratio of ferric oxide to sodium cyanide of 11.
Sodium cyanide is water-reactive. Sodium cyanide decomposes on contact with acids, acid salts, water, moisture, and carbon dioxide, producing highly toxic, flammable hydrogen cyanide gas. Sodium cyanide solution in water is a strong base it reacts violently with acid and is corrosive. Sodium cyanide is incompatible with strong oxidants.
