How is table salt iodized What is the percentage of added salt to convert non-iodized salt into iodized salt Which one sodium iodide or potassium iodide is more commonly used?

Answer 1

Table salt is iodized by adding a small amount of iodine, typically in the form of potassium iodide or sodium iodide, to non-iodized salt. The common percentage of iodine added is about 0.01% to 0.1% of the salt's weight, which translates to roughly 20-40 mg of iodine per kilogram of salt. Potassium iodide is more commonly used in iodization processes due to its stability and solubility.
