Manganese(II) iodide is the chemical compound composed of manganese and iodide with the formula MnI 2 (H2O) n. The tetrahydrate is a pink solid while the anhydrous derivative is beige. [2] Both forms feature octahedral Mn centers. Unlike MnCl 2 (H 2 O) 4 and MnBr 2 (H 2 O) 4 which are cis, MnI 2 (H 2 O) 4 is trans. [3]
An iodate is the polyatomic anion with the formula IO − 3. It is the most common form of iodine in nature, as it comprises the major iodine-containing ores. [ 1 ] Iodate salts are often colorless.

Potassium periodate can be prepared by the oxidation of an aqueous solution of potassium iodate by chlorine and potassium hydroxide. [1] KIO 3 + Cl 2 + 2 KOH → KIO 4 + 2 KCl + H 2 O. It can also be generated by the electrochemical oxidation of potassium iodate, however the low solubility of KIO 3 makes this approach of limited use.

Manganese(IV) oxide (manganese dioxide, MnO 2) is used as a reagent in organic chemistry for the oxidation of benzylic alcohols (where the hydroxyl group is adjacent to an aromatic ring). Manganese dioxide has been used since antiquity to oxidize and neutralize the greenish tinge in glass from trace amounts of iron contamination. [ 45 ]
