Water’s Polarity. One of water’s important properties is that it is composed of polar molecules: the hydrogen and oxygen within water molecules (H 2 O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, …Because water is polar, it is an exceptionally good solvent. In part this is because it can interact using additional types of intermolecular forces. These include dipole-induced dipole interactions between polar and non-polar substances, and ion-dipole interactions between ions and polar substances. The properties of water make it suitable for organisms to survive in during differing weather conditions. Ice freezes as it expands, which explains why ice is able to float on liquid water.
