The I2 molecules in iodine are not very soluble in water because they are not alike. I2 is non-polar whereas H2O is polar. But KI solution contains I- ions which combine with the I2 molecules to form I3- ions because these are charged they dissolve in the water which is a polar solvent.

The 12 molecules in iodine are not very soluble in water because they are not alike.12 in non-polar whereas H2O is polar .But KI solution contains 1-ions which combine with the 12 molecules to form 13-ions because these are charged they dissolve in the water which is a polar solvent
