Iodine sulfate

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.
