Metaperiodic acid

Metaperiodic acid, sodium salt [Sodium metapenodate], 55,68 Methane, bromo-, 55, 63 Methane, chlorodiphenyl- [Methyl chloride, diphenyl-], 55, 94... [Pg.148]

Only four of the acids listed in Table 19.8 have been isolated in pure form perchloric acid (HC104), iodic acid (HIO3), and the two periodic acids, metaperiodic acid (HI04) and paraperiodic acid (H5IC>6). The others are stable only in aqueous solution or in the form of their salts. Chlorous acid (HCIO2) is the only known halous acid. [Pg.849]

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]

Metaperiodic acid is a strong monoprotic acid, whereas paraperiodic acid is a weak polyprotic acid (Kal = 5.1 X 10-4 ka2 = 4.9 X 10-9). It has an octahedral structure in which a central iodine atom is bonded to one O atom and five OH groups ... [Pg.850]

The structure of H7I3O14 does not show any new type of catenation, because this compound exists in the solid state as a stoichiometric phase containing orthoperiodic and metaperiodic acids according to the formula (H0)sI0-2HI04. [Pg.668]
