Iodine differs from the other halogens because it forms more than one perhalic acid. Paraperiodic acid (HsIOg) is obtained as white crystals (mp 128°C) when periodic acid solutions are evaporated. When heated to 100°C at reduced pressure, these crystals lose water and are converted to metaperiodic acid (HIO4) ... [Pg.849]

Chlorine and bromine do not form perhalic acids of the type H5XO6 because their smaller sizes favor a tetrahedral structure over an octahedral one. [Pg.850]

The compounds I(OH)6(ONa), OI(OH)3,02I(0Ag)3, and OjI(OAg) are known, corresponding to the theoretical perhalic acids. Those corresponding to the halic acids are 02Br(0H) bromic acid, and I(OH) and 02I(0H), iodic acids. Br(ONa) and I(ONa), named respectively hypo-bromite and hypoiodite of sodium, are also known.

The perhalic acids and their anions are strong oxidising agents, especially Br04-, which is not thermodynamically stable in aqueous solution. They do, however have considerable kinetic stability. Perchlorates of organic or organometallic cations are very dangerous as they may appear stable, but can explode unpredictably with extreme force. [Pg.180]

Chlorous acid, HCIO2, is the only known halous acid. All the halogens except fluorine form halic and perhalic acids. The Lewis structures of the chlorine oxoacids are... [Pg.862]

For a given halogen, the acid strength decreases from perhalic acid to hypohalous acid the explanation of this trend is discussed in Section 15.9. [Pg.862]
