The compound name for KiO3 is Potassium Iodate.
Potassium iodate (KIO3) is an important inorganic compound widely recognized for its various applications. It is an ionic compound formed from the electrostatic attraction between a potassium cation (K+) and an iodate anion (IO3–). These ions combine in a 1:1 ratio, resulting in the neutral chemical formula KIO3.
Understanding Potassium Iodate (KIO3)
Potassium iodate is a white crystalline solid at room temperature. Its structure and chemical properties are derived from the individual ions that compose it.
- Potassium (K+): A Group 1 alkali metal, it readily loses one electron to form a positively charged cation.
- Iodate (IO3–): A polyatomic anion consisting of one iodine atom bonded to three oxygen atoms, carrying a net charge of -1.
The formation of KIO3 involves these ions combining in a precise manner to achieve electrical neutrality.

Common Uses and Applications
Potassium iodate has several practical applications across various industries, primarily due to its properties as an oxidizing agent and a source of iodine.
- Food Fortification: One of its most significant uses is in the iodization of salt, particularly in countries where iodine deficiency is prevalent. Iodine is a crucial micronutrient required for proper thyroid function and overall human health. While potassium iodide is more commonly used, potassium iodate is preferred in some regions due to its greater stability in humid and hot climates.
- Analytical Chemistry: It is used as a volumetric reagent in iodometric titrations, particularly for determining the concentration of reducing agents.
- Medicine: In some medical contexts, it can be used as a prophylactic agent to block radioactive iodine uptake by the thyroid gland, especially in nuclear emergencies, similar to potassium iodide.
- Laboratory Reagent: Employed in various laboratory experiments and syntheses.
Understanding the compound name and its fundamental properties is essential for anyone working with or studying this versatile chemical.
