Chemical compound

Barium iodate is an inorganic chemical compound with the chemical formula Ba(IO3)2. It is a white, granular substance.

Derivation

Barium iodate can be derived either as a product of a reaction of iodine and barium hydroxide or by combining barium chlorate with potassium iodate.

Chemical properties

The compound is stable on a temperature up to approximately 580 °C (1,076 °F). If the temperature is higher than that value, the following reaction, known as Rammelsberg's reaction, occurs:

5 Ba(IO3)2 → Ba5(IO6)2 + 9 O2 + 4 I2
