Natriumaate

Natriumaate is the common name for sodium iodate, a chemical compound with the formula NaIO3. It is a white, crystalline solid that is soluble in water. Sodium iodate is an oxidizing agent and can react with reducing agents.

Sodium iodate is used in various applications. It is commonly found in iodized salt, which is used to prevent iodine deficiency disorders. In analytical chemistry, it is used as a titrant in redox titrations. It also finds use in the synthesis of other iodine compounds and as a component in some fireworks and pyrotechnic compositions. Historically, it has been employed as a food additive and as a disinfectant.

The production of sodium iodate typically involves the reaction of iodine with a sodium hydroxide solution. Under oxidizing conditions, this reaction yields sodium iodate. Alternatively, it can be produced by the electrolysis of a sodium iodide solution.

While generally considered safe in the quantities used in food, sodium iodate can be irritating to the skin, eyes, and respiratory tract in its concentrated form. Ingestion of large amounts can lead to symptoms of iodine poisoning, including gastrointestinal upset, fever, and thyroid dysfunction. It is important to handle sodium iodate with appropriate safety precautions, including wearing protective gloves and eyewear.
