Answer:
Ion-dipole attraction force pulls
into solution
Step-by-step explanation:
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
ions through its negatively charged polarized end and
through its positively charged polarized end.
At equilibrium, this ion-dipole attraction force overcome the ionic interaction present between
and
.
Hence KI become soluble into water.
