Question

preparation of cyanide

Answer 1

A cyanide is a chemical compound that contains the group C≡N. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom.[1]

In inorganic cyanides, the cyanide group is present as the anion CN−. For the salts such as sodium cyanide and potassium cyanide, these compounds are highly toxic.[2] Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts
