This article is about the compound I2O. For the molecule IO, see Iodine monoxide.
Chemical compound
Diiodine oxide, also known as iodo hypoiodite, is an oxide of iodine that is equivalent to an acid anhydride of hypoiodous acid. This substance is unstable and it is very difficult to isolate.[2]
Preparation
Diiodine oxide can be prepared by reacting iodine with potassium iodate (KIO3) in 96% sulfuric acid and then extracting it into chlorinated solvents.[2]
Reactions
Diiodine oxide reacts with water to form hypoiodous acid:
- I2O + H2O → 2 HIO
