Sodium cyanide is a weak salt acid that is highly poisonous and used widely in the mining industry.

Sodium cyanide (NaCN) is an inorganic compound (does not establish carbon and hydrogen bond) used in the mining industry, making dyes, cleaning metals, and preparing nitriles. It is also highly demanding as a test reagent for the functioning of chemoreceptors and in industrial processes. It can be prepared by reacting hydrogen cyanide (HCN) with sodium hydroxide (NaOH) and gives a faint odor of bitter almonds. Sodium cyanide is also known as Cyanide of sodium or Cyanogen. It contains sodium and a one-carbon compound. It is an ionic compound that contains sodium cat-ion and cyanide anion, and carbon forms a triple bond with nitrogen to adopt a crystalline structure like sodium chloride.
