Sodium cyanide solution in water is a strong base it reacts violently with acid and is corrosive. Sodium cyanide is incompatible with strong oxidants. Carbon dioxide from the air is sufficiently acidic to liberate toxic hydrogen cyanide gas on contact with sodium cyanide.

Applications:
- Sodium cyanide is used as a starting material for the preparation of Reissert compounds, cyanogen bromide, cyanuric chloride and cyanogen chloride.
- It acts as a catalyst for the aminolysis of esters to primary amides. Furthermore, it is used for fumigation, in electroplating and for extracting gold and silver in mining industry. In organic synthesis, it is involved in the cyanation reaction of alkyl halides under phase transfer conditions.Extracting gold and silver from ores; electroplating baths; case hardening steel by liquid nitriding; manufacture of hydrocyanic acid and other cyanides.
- Sodium cyanide is used for electroplating metals such as zinc, copper, cadmium, silver, and gold, and their alloys; for extracting gold and silver from ores; and as a fumigant and a chelating agent.
- It occurs in many varieties of maniocs (cassava), especially in bitter manioc.
- sodium cyanide and other water-soluble cyanides are used as modifying reagents for selective flotation of ores containing galena, sphalerite and gangue minerals.
