Potassium iodate

The analogous reaction with potassium hypochlorite is also possible:[3]KI + 3KOCl → 3KCl + KIO3Conditions/substances to avoid include: heat, shock, friction,[4] combustible materials,[1] reducing materials, aluminium,[4] organic compounds,[1] carbon, hydrogen peroxide and sulfides.

In the US, iodized salt contains antioxidants, because atmospheric oxygen can oxidize wet iodide to iodine; other countries simply use potassium iodate instead.

[10] The UK, Singapore, United Arab Emirates, and the U.S. states Idaho and Utah all maintain potassium iodate tablets towards this end.

[citation needed] Following the September 11 attacks, the government of Ireland issued potassium iodate tablets to all households for a similar purpose.

[13][14] Potassium iodate is an oxidizing agent and as such it can form explosive mixtures when combined with organic compounds.

NFPA 704 four-colored diamond Health 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. E.g. chloroform Flammability 0: Will not burn. E.g. water Instability 2: Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water. E.g. white phosphorus Special hazard OX: Oxidizer. E.g. potassium perchlorate
