The fortificant used in iodized salt is

  • A.Sodium iodide
  • B.Potassium iodate
  • C.Sodium iodate
  • D.Potassium iodide

Answer: B

The fortificant used in iodised salt is potassium iodate.

Under the Indian programme the salt is fortified with potassium iodate, since it is much more stable than potassium iodide in the heat, humidity and impurities of tropical storage and transport. Potassium iodide loses iodine by oxidation and volatilisation, which is why it is no longer preferred. Sodium iodide and sodium iodate are not the compounds used in the national programme.
