Oxyacids of iodine are:
- iodic acid: HIO3
- iodous acid: HIO2
- hypoiodous acid: HIO
- ortho periodic acid: HIO4
- meta periodic acid: H5IO6
Iodine is also known as I2 or iodide in its ionic form. It is sometimes referred to as molecular iodine.
The chemical formula for potassium iodine is KI
Formula: I2
The three states of iodine are solid, liquid, and gas. At room temperature, iodine is a solid with a dark purple color. When heated, it sublimes directly from a solid to a purple-violet gas.
in my opinion flourine is very electronegative and it cannot exist in positive oxidation states in its compounds .in oxyacids of halogens ,oxygen carries a negative charge while the halogen carries a positive charge.the electronegativity of flourine is 4,while that of oxygen is 3.5. so due to high value of electronegativity ,flourine shows reluctance to form positive oxidation states and donot form oxyacids........
Examples: nitric acid, sulfuric acid, phosphoric acid, perchloric acid, etc.
Iodine is the only name in English.
Fluorine can not form oxyacids because fluorine is more electronegative than oxygen, and oxyacids are formed only from elements that are less electronegative than oxygen.

aluminium is passive towards oxyacids due to formation of protevtive layer of oxide. this protective layer resists the contact of aluminium with water or oxygen thatswhy aluminium is passive towards oxyacids
The chemical formula for potassium iodine is KI
Formula: I2
Iodine can form at least three oxides, with formulas IO2, I2O5, and I4O9. The first one of these is sometimes written as a dimer, with formula I2O4.
