Is kio3 primary standard

Potassium iodate (KIO3) is considered a primary standard for iodine in redox titrations because it is stable, highly pure, and can be accurately weighed. It does not absorb moisture from the air, making it easy to handle and use in quantitative analyses. Additionally, KIO3 can be converted to iodine in a reaction, providing a reliable source for standardizing iodine solutions.
