Iodine sulfate is an inorganic compound with the formula I2(SO4)3. It appears as light yellow crystals and reacts with water.
Synthesis
Reaction of diiodosyl sulfate and sulfur trioxide:
- (IO)2SO4 + 2 SO3 → I2(SO4)3
Iodine sulfate is also produced when elemental I2 , I2O5 and SO3 react.
Physical properties
Iodine sulfate forms light yellow hygroscopic crystals.
Chemical properties
Iodine sulfate is soluble in organic liquids and stable in anhydrous and strongly acidic solvents. In a humid environment, it darkens due to decomposition that releases molecular 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. 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.
