Answer:
Ion-dipole attraction force pulls [tex]I^{-}[/tex] into solution
Explanation:
[tex]I^{-}[/tex] is an anion and water molecule is dipolar due to polarization of bonded electron towards more electronegative oxygen atom.
Hence, when KI is added in water, water molecule attracts [tex]K^{+}[/tex] ions through its negatively charged polarized end and [tex]I^{-}[/tex] through its positively charged polarized end.
At equilibrium, this ion-dipole attraction force overcome the ionic interaction present between [tex]K^{+}[/tex] and [tex]I^{-}[/tex].
Hence KI become soluble into water.
