What has a higher boiling point water or KI?
Potassium iodide has a higher boiling point because it is ionically bonded while water is polar covalent (with hydrogen bonds). The ionic bonds on KI are stronger than the bonds of water. This means that the molecules are “stuck” to each other stronger than water’s molecules. Then it would take more energy (heat) to “unstick” them to change its state of matter, resulting in a higher boiling point.
