What is Periodic acid?
'''Periodic acid''' (pronounced as per·io'·dic acid) is a [[chemical compound]]. It is also an [[acid]]. Its [[chemical formula]] is HIO<sub>4</sub> or H<sub>5</sub>IO<sub>6</sub>. It has [[hydrogen]] and [[periodate]] [[ion]]s in it. ==Properties== Periodic acid is found as a colorless [[solution]]. It is a strong [[oxidizing agent]], like [[perchloric acid]]. It breaks down when heated to [[iodine pentoxide]] and [[oxygen]], as well as water. It does not form I<sub>2</sub>O<sub>7</sub>. It is found as HIO4 in dilute solution and H5IO6 in concentrated solution. When H5IO6 is heated, it turns into HIO4. ==Preparation== It is made by reacting a periodate with a [[strong acid]]. ==Uses== It is used to look at the structure of certain [[organic chemistry|organic]] compounds. ==Related pages== *[[Perbromic acid]] *[[Sodium perbromate]] *[[Iodic acid]] [[Category:Iodine compounds]] [[Category:Acids]]
