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.[1]

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:[2]

\mathrm {5Ba(IO_{3})_{2}\longrightarrow \;Ba_{5}(IO_{6})_{2}+9O_{2}+4I_{2}}

gollark: Why bother with all the collection nonsense, just name stuff!

gollark: No, I mean, if you name your dragon using the naming option with `Wyrm` in its name, it should count.

gollark: Dragons with `Wyrm` in their name - not their breed name, their name - should count.

gollark: _pets with whatever ridiculously strong gloves are used to handle magmas and stuff_

gollark: I'm going to bed soonish. If the hatchery explodes, please ping me.
