Iodine sulfate is an inorganic compound of iodine and sulfuric acid with the formula I2(SO4)3.[1] It appears as light yellow crystals and reacts with water.
Synthesis
[edit]Reaction of diiodosyl sulfate and sulfur trioxide:[2][3]
- (IO)2SO4 + 2 SO3 → I2(SO4)3
Iodine sulfate is also produced when elemental I2 , I2O5 and SO3 react.[4]
Physical properties
[edit]Iodine sulfate forms light yellow hygroscopic crystals.[2]
Chemical properties
[edit]Under the influence of atmospheric moisture it darkens due to the release of iodine.

According to the equation: (IO)2SO4 + 2SO3 = I2(SO4)3 ... the yellow crystals could be isolated. They showed properties typical of a neutral iodine salt, being specially sensitive to moisture. [Fichter et al.] showed that the compound was mainly neutral iodine sulphate I2(SO4)3 ... the neutral salts have a much lighter yellow colour[,] a greater solubility in organic liquids and a greater sensitivity to water.
