|Section2= |Section7= |Section8= }} Potassium iodate (KIO3) is a chemical compound. It is ionic, made up of K+ ions and IO3− ions in a 1:1 ratio. ==Chemical properties== 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: :HIO3 + KOH → KIO3 + H2O It can also be prepared by adding iodine to a hot, concentrated solution of potassium hydroxide. :3 I2 + 6 KOH → KIO3 + 5 KI + 3 H2O Or by fusing potassium iodide with potassium chlorate, bromate or perchlorate, the melt is extracted with water and potassium iodate is isolated from the solution by crystallization:〔Pradyot Patnaik.

McGraw-Hill, 2002, ISBN 0-07-049439-8〕 :KI + KClO3 → KIO3 + KCl Conditions/substances to avoid include: heat, shock, friction, combustible materials, reducing materials, aluminium, organic compounds, carbon, hydrogen peroxide and sulfides. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Potassium iodate」の詳細全文を読む スポンサード リンク
