Question

Using knowledge of intermolecular forces, explain why the yellow food coloring mixed with the water and the acetone was able to remove the blue dye from the glitter.

(Basically the experiment was we mixed yellow food coloring with acetone and water and added it to glitter, and it removed the blue dye from the glitter. Please mention intermolecular forces in your answer.)

Answer 1

The yellow coloring is a polar substance hence it dissolve in water. Blue dye is nonpolar hence it dissolves in less polar acetone.

In chemistry, there is a general rule that like dissolves like. A substance can only dissolve in another if there is some kind of intermolecular interaction between the substances.

The yellow food coloring is a polar substance hence it is able to dissolve in water which is a polar solvent. The blue dye is a nonpolar substance hence it dissolve in acetone which is a less polar solvent.
