Periodate (/ pəˈraɪ.ədeɪt / pə-RY-ə-dayt) is an anion composed of iodine and oxygen. It is one of a number of oxyanions of iodine and is the highest in the series, with iodine existing in oxidation state +7. Unlike other perhalogenates, such as perchlorate, it can exist in two forms: metaperiodate IO−. 6.
Sodium periodate is an inorganic salt, composed of a sodium cation and the periodate anion.It may also be regarded as the sodium salt of periodic acid.Like many periodates, it can exist in two different forms: sodium metaperiodate (formula NaIO 4) and sodium orthoperiodate (normally Na 2 H 3 IO 6, but sometimes the fully reacted salt Na 5 IO 6).
Periodic acid (/ ˌpɜːraɪˈɒdɪk / per-eye-OD-ik) is the highest oxoacid of iodine, in which the iodine exists in oxidation state +7. It can exist in two forms: orthoperiodic acid, with the chemical formula H5IO6, and metaperiodic acid, which has the formula HIO4. Periodic acid was discovered by Heinrich Gustav Magnus and C. F. Ammermüller ...
Infobox references. Potassium periodate is an inorganic salt with the molecular formula KIO 4. It is composed of a potassium cation and a periodate anion and may also be regarded as the potassium salt of periodic acid. Note that the pronunciation is per-iodate, not period-ate.
Iodate is one of several oxyanions of iodine, and has an oxidation number of +5. It participates in several redox reactions, such as the iodine clock reaction. Iodate shows no tendency to disproportionate to periodate and iodide, in contrast to the situation for chlorate. Iodate is reduced by sulfite: [1]
Potassium periodate: ... Potassium iodate (K I O 3) is an ionic inorganic compound with the formula KIO 3. It is a white salt that is soluble in water. [1]
Periodatonickelates. The periodatonickelates are a series of anions and salts of nickel complexed to the periodate anion. The most important of these salts are the diperiodatonickelates, in which nickel exhibits the +4 oxidation state: these are powerful oxidising agents, capable of oxidising bromate to perbromate .
The main use of sodium iodate in everyday life is in iodised salt. The other compounds which are used in iodised table salt are potassium iodate, potassium iodide, and sodium iodide. Sodium iodate comprises 15 to 50 mg per kilogram of applicable salt. Sodium iodate is also used as a dough conditioner to strengthen the dough.
