An article about the iodate ion in chemistry

Iodate[edit]

The iodate ion is a polyatomic ion with the chemical formula IO__. It is the conjugate base of iodic acid (HIO_) and is commonly encountered in various chemical reactions and compounds. The iodate ion is an important species in inorganic chemistry and is known for its oxidizing properties.

Structure[edit]

The iodate ion consists of one iodine atom centrally bonded to three oxygen atoms in a trigonal pyramidal arrangement. The iodine atom is in the +5 oxidation state, and the ion carries a net charge of -1. The geometry of the iodate ion is similar to that of the chlorate and bromate ions, which are also oxyanions of the halogens.

Properties[edit]

Iodate ions are strong oxidizing agents and can participate in various redox reactions. They are stable in aqueous solutions and can be reduced to iodide ions (I_) or oxidized to periodate ions (IO__) under appropriate conditions. The iodate ion is less reactive than the hypoiodite (IO_) and iodite (IO__) ions but more reactive than the periodate ion.

Occurrence[edit]

Iodate ions are found naturally in some minerals and are also produced industrially. They are used in the production of iodized salt, where potassium iodate (KIO_) is added to table salt to prevent iodine deficiency.

Uses[edit]

Iodate compounds are used in various applications, including:

As an oxidizing agent in analytical chemistry.
In the food industry as a source of iodine in iodized salt.
In the synthesis of other iodine-containing compounds.
