Question

Iodine is more soluble in KI than in water.Explain?

Answer 1

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.
