—
Aqueous solution of potassium cyanide (KCN) — colorless crystals dissolved in water, forming liquid potassium cyanide. Used in electroplating (gilding, silvering), gold mining, organic synthesis, and laboratory processes. It is an extremely potent poison with instantaneous action, similar in toxicity to hydrocyanic acid (HCN). Primary mechanism of action is blockade of cytochrome oxidase enzyme in mitochondria.
