Water is a "polar" molecule, meaning that there is an uneven distribution of electron density.
Water has a partial negative charge () near the oxygen atom due the unshared pairs of electrons, and partial positive charges () near the hydrogen atoms.
An electrostatic attraction between the partial positive charge near the hydrogen atoms and the partial negative charge near the oxygen results in the formation of a hydrogen bond.
The ability of ions and other molecules to dissolve in water is due to polarity. For example, sodium chloride in its crystalline form will dissolve in water.
A water molecule is polar, which is why it attracts other polar molecules.
Water is a polar molecule, polar molecules are more soluble in other polar molecules. Oxygen helps make organic molecules more polar, and therefore more soluble in water.
Do water molecules in the liquid state have more energy than water molecules in the polar state
Molecules that are polar(charged) dissolve best in water, while nonpolar molecules do not dissolve well in water.
Polar Molecules
Polar molecules dissolve in water. The reason why polar molecules dissolve in water, but not non-polar molecules is because non-polar molecules can't form hydrogen bonds.
Polar molecules are mixed better with water.
Water attracts polar molecules and repels non-polar molecules because water has polar molecules. Water does have a net dipole though it doesn't have net charge.
Water is polar while oils are non-polar. Molecules that are polar will mix with other polar molecules, and non-polar molecules will mix with other non-polar molecules. Polar and non-polar molecules will not mix.
It dissolves all kinds of molecules. However, the ones that it dissoves well are molecules that it can hydrogen bond with or molecules that are polar that it can have dipole-dipole interactions with.
A water molecule is polar, which is why it attracts other polar molecules.
Hydrophobic molecules do not dissolve in water. This is because water is hydrophilic. Another way to say this is that lipids, which are nonpolar, cannot dissolve in water, which in polar.
Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
Because water is polar, and polar solvants will dissolve polar solutes. :)
They are polar

Water molecules are uncharged and polar.
