The cyanide ion is a reductant and is oxidized by strong oxidizing agents such as molecular chlorine (Cl 2), hypochlorite (ClO −), and hydrogen peroxide (H 2 O 2). These oxidizers are used to destroy cyanides in effluents from gold mining .
There are two possible structures for hydrogen cyanide, HCN and CNH, differing only as to the position of the hydrogen atom. The structure with hydrogen attached to nitrogen, CNH, leads to formal charges of -1 on carbon and +1 on nitrogen, which would be partially compensated for by the electronegativity of nitrogen and Pauling calculated the net charges on H, N and C as -0.79, +0.75 and +0.04 ...
Cyanogen is typically generated from cyanide compounds. One laboratory method entails thermal decomposition of mercuric cyanide: . 2 Hg(CN) 2 → (CN) 2 + Hg 2 (CN) 2 Or, one can combine solutions of copper(II) salts (such as copper(II) sulfate) with cyanides; an unstable copper(II) cyanide is formed which rapidly decomposes into copper(I) cyanide and cyanogen.
A hydrogen cyanide concentration of 100–200 ppm in breathing air will kill a human within 10 to 60 minutes. [68] A hydrogen cyanide concentration of 2000 ppm (about 2380 mg/m 3) will kill a human in about one minute. [68] The toxic effect is caused by the action of the cyanide ion, which halts cellular respiration.
Cyanogen azide is a chemical compound with the chemical formula C N 4, or more precisely − N=N + =N−C≡N. It is an azide compound of carbon and nitrogen. It is an oily, colourless liquid at room temperature. [2] It is a highly explosive chemical that is soluble in most organic solvents, and normally handled in dilute solution in this form.
Models of Titan's atmosphere had predicted that HCNH + would be the dominant ion present, and a strong peak in the mass spectrum at m / z = 28 seems to support this theory. In 1997, observations were made of the long-period comet Hale–Bopp in an attempt to find HCNH + , [ 20 ] but it was not detected.
Any salt containing the ion, such as ammonium cyanate, is called a cyanate. The cyanate ion is an isomer of the much-less-stable fulminate anion, CNO − or [C − ≡N + −O −]. [1] The cyanate ion is an ambidentate ligand, forming complexes with a metal ion in which either the nitrogen or oxygen atom may be the electron-pair donor.
