Potassium iodate Potassium iodate Potassium iodate (KIO) is a chemical compound. It is ionic, made up of K ions and IO ions in a 1:1 ratio. Potassium iodate is an oxidizing agent and as such it can cause fires if in contact with combustible materials or reducing agents. It can be prepared by reacting a potassium-containing base such as potassium hydroxide with iodic acid, for example: It can also be prepared by adding iodine to a hot, concentrated solution of potassium hydroxide. Or by fusing potassium iodide with potassium chlorate, bromate or perchlorate, the melt is extracted with water and potassium iodate
Potassium oxide potassium oxide. Thus, if a fertilizer is 30% potassium chloride by weight, its standard potassium rating, based on potassium oxide, would be only 18.8%. Potassium oxide Potassium oxide (KO) is an ionic compound of potassium and oxygen. This pale yellow solid, the simplest oxide of potassium, is a rarely encountered, highly reactive compound. Some materials of commerce, such as fertilizers and cements, are assayed assuming the percent composition that would be equivalent to the chemical compound mixture KO. Potassium oxide is produced from the reaction of oxygen and potassium; this reaction affords potassium oxide, KO. Treatment of the peroxide with
