STRONTIUM IODATE Chemical Properties,Usage,Production

Description

Strontium Iodate can be prepared by the reaction of iodic acid upon the carbonate:
SrCO3＋2HIO3→Sr(IO3)2＋CO2＋H2O
The product is either a monohydrate or a hexahydrate (like the calcium homologue).

Chemical Properties

Physical properties

Strontium iodate monohydrate, Sr(IO3)2·H2O has the solubility product of 3.77×10^-7 while the value of strontium iodate hexahydrate, Sr(IO3)2·6H2O, is 4.55×10^-7.The hexahydrate is a crystalline powder that is slightly soluble in water but is soluble in dilute nitric acid where it forms the nitrate plus iodine. The solubility of this salt in water is 0.19 g/100 ml at 20°C and 0.35 g/100 ml at 100°C. The magnetic susceptibility of the salt is 108 g/10^-6 cm3/mol.
