Cyanide is usually found joined with other chemicals to form compounds. Examples of simple cyanide compounds are hydrogen cyanide, sodium cyanide and potassium cyanide. Certain bacteria, fungi, and algae can produce cyanide, and cyanide is found in a number of foods and plants. In certain plant foods, including almonds, millet sprouts, lima beans, soy, spinach, bamboo shoots, and cassava roots (which are a major source of food in tropical countries), cyanides occur naturally as part of sugars or other naturally-occurring compounds. However, the edible parts of plants that are eaten in the United States, including tapioca which is made from cassava roots, contain relatively low amounts of cyanide. Hydrogen cyanide is a colorless gas with a faint, bitter, almondlike odor. Sodium cyanide formula and potassium cyanide are both white solids with a bitter, almond-like odor in damp air. Cyanide and hydrogen cyanide are used in electroplating, metallurgy, organic chemicals production, photographic developing, manufacture of plastics, fumigation of ships, and some mining processes.
hydrogen cyanide is a colorless or pale-blue liquid (hydrocyanic acid); at higher temperatures, it is a colorless gas. Hydrogen cyanide is very volatile, producing potentially lethal concentrations at room temperature. The vapor is flammable and potentially explosive. Hydrogen cyanide has a faint, bitter almond odor and a bitter, burning taste. It is soluble in water and is often used as a 96% aqueous solution.
Sodium cyanide appears as a white crystalline solid, lump solid or powder. A deadly human poison by ingestion. Toxic by skin absorption through open wounds, by ingestion, and by inhalation of dust.
Sodium cyanide solution appears as a clear colorless aqueous solution.
Sodium cyanide is a cyanide salt containing equal numbers of sodium cations and cyanide anions. It has a role as an EC 1.15.1.1 (superoxide dismutase) inhibitor. It is a cyanide salt, a one-carbon compound and a sodium salt.
Sodium Cyanide is a toxic cyanide salt, sodium salt, and one-carbon compound that is used as an insecticide, a test reagent for the function of chemoreceptors, and in many industrial processes. It is characterized as a white crystalline solid, colorless gas, or aqueous solution that is odorless or has a faint, bitter almond-like odor. Exposure occurs by inhalation, ingestion, or contact.
Sodium cyanide is a chemical compound of sodium and cyanide. It is used mainly in gold mining. (L104)

A highly poisonous compound that is an inhibitor of many metabolic processes and is used as a test reagent for the function of chemoreceptors. It is also used in many industrial processes.
