Physical properties
The monohydrate occurs
as lustrous, monoclinic crystals or a white crystalline
powder. It is somewhat soluble in hot water but slightly
in cold water. It is insoluble in sulfuric acid or alcohol. It loses its water of hydration at 130°C.The solubility product of the monohydrate at 25°C is 2.7×10
-9. This salt is not used in Industry but is offered
for sale commercially in limited quantities.
Preparation
Barium Iodate can be
prepared by the reaction of iodic acid upon the carbonate:
BaCO3 ＋2HIO3→Ba(IO3)2 ＋CO2＋H2O
The product is either a monohydrate or a hexahydrate
(like the calcium homologue).
