  1. Definition of KCN
    KCN, also known as Potassium cyanide, is a chemical compound belonging to the category of potassium cyanide salts, with the chemical formula KCN. The atomic mass of KCN is 65.12 g/mol. Its atomic weight consists of 1 potassium atom, 1 carbon atom, and 1 nitrogen atom. KCN does not have a distinct ionic structure, when it dissolves in water or other polar solvents, KCN will dissociate into K+ and CN- ions.

  2. Properties
    2.1 Physical properties: KCN is a solid, colorless, odorless substance when in a dry state but if damp, it has an irritating odor. Especially, KCN is an extremely toxic substance, which can cause death if overexposed. The pH level of the KCN solution is usually very alkaline, about 11-12.
    2.2 Chemical properties: KCN has the ability to react with many other substances such as metals, acids, non-metals, and salts to form various different compounds.

  3. Common chemical equations: KCN can react with metals such as gold, silver; react with acids such as HCl, H2SO4; react with non-metals such as O2, Cl2; react with salts such as NaCl, KCl to form different compounds.

  4. Preparation of KCN
    4.1 Laboratory preparation: KCN can be prepared from the reaction of KCNO with C.
    4.2 Industrial preparation: KCN is usually produced from the reaction between ammonia, oxygen, and coal under high pressure and high temperature.
