Sodium iodate, represented by the chemical formula NaIO3, is an inorganic compound composed of sodium, iodine, and oxygen. It appears as a white crystalline solid and is commonly used in various applications, including as a reagent in chemical analysis and in the production of iodine. In addition to its laboratory uses, NaIO3 can also serve as a food additive, particularly in the preservation of certain foods. It is important to handle sodium iodate with care, as it can be toxic in large quantities and may pose health risks if ingested improperly.
