IODATE - IODIDE
Iodate Usage Areas
​
1. Water Disinfection: Iodate, particularly in the form of potassium iodate, can be used for water disinfection in emergency situations or in areas where traditional disinfection methods are not feasible.
2. Iodization of Salt: Potassium iodate is often used to iodize table salt. This process is crucial for preventing iodine deficiency disorders in populations where iodine intake might be low due to soil depletion or diet.
3. Bakery Industry: Potassium iodate can be used as a dough conditioner in the bakery industry, improving the texture and volume of bread. However, its use is subject to regulation and is banned in some countries due to health concerns.
4. Analytical Chemistry: Iodates are used in analytical chemistry for quantitative analysis and as oxidizing agents in various chemical reactions.
5. Agriculture: Iodate can be utilized in agriculture to enrich fertilizers with iodine, promoting iodine uptake in plants and, consequently, increasing dietary iodine in humans when these plants are consumed.

Iodide Usage Areas
1. Medical Treatments and Supplements: Iodide, especially potassium iodide, is used in medical treatments to manage thyroid conditions. It's also included in dietary supplements to prevent iodine deficiency, which is crucial for thyroid health.
2. Radiation Protection: Potassium iodide is used as a protective agent in nuclear emergencies. It helps prevent the thyroid gland from absorbing radioactive iodine, thereby protecting it from radiation damage.
3. Photography: Silver iodide is a key component in traditional photography, where it is used in the emulsion on photographic films and paper due to its sensitivity to light.
​
4. Organic Synthesis: In chemistry, iodides serve as a starting material for the synthesis of various organic compounds, including pharmaceuticals and agrochemicals, due to their reactivity.
5. Food Stabilizers and Colorants: Iodide compounds are used in the food industry as stabilizers and colorants, enhancing the shelf life and appearance of food products.
​
Both iodide and iodate play significant roles in environmental, health, and industrial applications. Their specific uses depend on their chemical properties, such as iodide's reducing ability and iodate's oxidizing potential. These compounds are essential in supporting human health, particularly in preventing iodine deficiency, and in various industrial processes.
