Differbetween
There are two forms of iodine that can be used to iodize salt: iodide and iodate, usually as the potassium salt. Iodate is less soluble and more stable than iodide and is therefore preferred for tropical moist conditions. Both are generally referred to as iodized salt.

What is potassium iodate used for?
Potassium Iodate tablets are used at the time of a nuclear emergency; the tablets stop the thyroid gland (situated in your neck) taking up radioactive iodine, which may be released into the environment following a nuclear accident. Radioactive Iodine is harmful and especially dangerous to babies and children.
What is a substitute for potassium iodide?
According to sources on the Internet, most supplies of KI are depleted and people are unable to purchase it. As an alternative, people may want to purchase Lugol's Solution, which is a combination of pure iodine, Potassium iodide, and water. One site that sells it is jcrows.com.
Why is potassium iodate more stable than iodine?
These two compounds are characterised by different chemical properties and some differencies in potential toxicity/safety. Iodate is more stable, as iodide is readily oxidized to iodine and lost by evaporation [5].
Is potassium iodate toxic?
Potassium iodate can produce retinal toxicity that damages RPE and photoreceptor cells.
Is potassium iodate bad?
But, when used inappropriately or unnecessarily, potassium iodide has the potential to cause very serious side effects such has abnormal heart rhythms, bleeding, nausea, vomiting, and electrolyte abnormalities. The risk of using KI far exceeds any benefit right now.
Can I buy potassium iodide?

Does iodine degrade?
Elemental iodine readily sublimes and is then rapidly lost to the atmosphere through diffusion. ... As in most chemical reactions, elevated temperature increases the rates of the reactions that form elemental iodine and increases the rate of evaporation of iodine.
Why is potassium iodate a good primary standard?
Potassium Iodate is an oxidizing agent and a good primary standard with the one drawback of having a relatively low equivalent weight. It is used primarily as a stable source of Iodine, which is liberated in the presence of Iodide ion and acid, in the titration of Thiosulfate and Sulfite solutions.
