Solubility of non polar liquids in polar solvents. (1 Viewer)

Explain why the solubility of the triiodide ion is more soluble in water than is iodone?

I understand they both have limited solubility in water, as they are non polar, but what specifically allows the triiodide ion to dissolve more than iodine?

Thanks!!

Ion. Charge. Interact with dipoles of water through ion-dipole forces = stronger IMF = more soluble.

Iodine. No charge. Dispersion forces only = weaker IMF = less soluble.
