ABOUT IS POTASSIUM CYANIDE POISONOUS

Potassium cyanide (KCN) was an important supply of alkali metallic cyanides ahead of the invention of the Castner approach. It had been produced by the decomposition of potassium ferrocyanide. The response is as follows:Cyanide is unstable in water, even so the reaction is slow till about one hundred seventy °C. It undergoes hydrolysis to provide
