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 pyrosulfate OSOSO. The oxidation state of sulfur in this compound is +6. Potassium pyrosulfate is used in analytical chemistry; samples are fused with potassium pyrosulfate, (or a mixture of potassium pyrosulfate and potassium fluoride) to ensure complete dissolution prior to a quantitative analysis. The compound is also present in a catalyst in conjunction with vanadium(V) oxide in the industrial production of sulfur trioxide. Potassium pyrosulfate Potassium pyrosulfate, or potassium disulfate, is an inorganic compound with the chemical formula KSO. Potassium pyrosulfate is obtained by the thermal decomposition of other salts, most directly from potassium bisulfate: Temperatures above 600°C further decompose potassium
