Potassium cyanide is a compound with the formula KCN. It is a colorless salt, similar in appearance to sugar , that is highly soluble in water. Most KCN is used in gold mining , organic synthesis , and electroplating .
Acute digitalis overdose such as digoxin toxicity may cause hyperkalemia [23] through the inhibition of sodium-potassium-ATPase pump. [15] Massive blood transfusion can cause hyperkalemia, especially in infants and patients with low glomerular filtration rate (GFR, a measure of kidney function) due to leakage of potassium out of the red blood ...
Jonestown, Guyana, was the site of a large mass murder–suicide, [76] in which over 900 members of the Peoples Temple drank potassium cyanide–laced Flavor Aid in 1978. Chicago Tylenol murders (1982) Timothy Marc O'Bryan (1966–1974) died on October 31, 1974, by ingesting potassium cyanide placed into a giant Pixy Stix.
Potassium is a chemical element; it has symbol K (from Neo-Latin kalium) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. [9] Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.
Potassium-40 (40 K) is a long lived and the main naturally occurring radioactive isotope of potassium. Its half-life is 1.25 billion years. It makes up about 0.012% ...
Potassium hexacyanidoferrate(II) can be used as a fertilizer for plants. [citation needed] Prior to 1900, before the invention of the Castner process, potassium hexacyanidoferrate(II) was the most important source of alkali metal cyanides. [6] In this historical process, potassium cyanide was produced by decomposing potassium hexacyanidoferrate ...
Among the most toxic cyanides are hydrogen cyanide (HCN), sodium cyanide (NaCN), potassium cyanide (KCN), and calcium cyanide (Ca(CN) 2). The cyanide anion is an inhibitor of the enzyme cytochrome c oxidase (also known as aa 3), the fourth complex of the electron transport chain found in the inner membrane of the mitochondria of eukaryotic ...
Toxicity may occur over a short period of time following an overdose or gradually during long-term treatment. [1] Risk factors include low potassium , low magnesium , and high calcium . [ 1 ] Digoxin is a medication used for heart failure or atrial fibrillation . [ 3 ]
