Explanation:
Edible salt can be iodised by spraying it with a potassium iodate or potassium iodide solution. 57 grams of potassium iodate, costing about US$1.15 (in 2006), is required to iodise a ton (2,000 pounds) of salt. Dextrose is added as a stabilizer to prevent potassium iodide from oxidizing and evaporating.
