Since I2IX2 is a non-polar covalent molecule, it does not ionize in water. It cannot also be soluble in the polar water.
KIKI, which is a polar, ionic compound, will ionize and dissolve in water. When KI dissolves in water, it ionizes to K+KX+ and I−IX−.
The I−IX− will react with I2IX2 to form the complex ion I3−IX3X−. I3−IX3X− being negatively charged will dissolve in water
