Potassium lid of the container, and can detonate upon opening. Because of the highly reactive nature of potassium metal, it must be handled with great care, with full skin and eye protection and preferably an explosion-resistant barrier between the user and the metal. Ingestion of large amounts of potassium compounds can lead to hyperkalemia, strongly influencing the cardiovascular system. Potassium chloride is used in the United States for lethal injection executions. Potassium Potassium is a chemical element with symbol K (from Neo-Latin "kalium") and atomic number 19. It was first isolated from potash, the ashes of plants, from which its name
Potassium ferrioxalate Potassium ferrioxalate Potassium ferrioxalate, also known as potassium trisoxalatoferrate(III), is a chemical compound with the formula [], where iron is in the +3 oxidation state. It is an octahedral transition metal complex in which three bidentate oxalate ions are bound to an iron center. Potassium acts as a counterion, balancing the −3 charge of the complex. Crystals of the trihydrated form of the complex, []·3, are emerald green in color. In solution, the salt dissociates to give the ferrioxalate anion, [], which appears fluorescent green in color. Potassium ferrioxalate is often used in chemical actinometry, i.e. the measure of light
