Question
Water is attracted to anything charged (ionized) or polar (slightly charged)
Recall that opposite charges attract.
Because of its partial positive and negative charges, water is attracted to molecules that are
charged or polar, including other water molecules.
The attraction between water molecules is a weak bond called a hydrogen bond.
These bonds are not just between water molecules though. These bonds can be between other
kinds of molecules too. For example, they hold two strands of DNA together!
Draw several water molecules aligned with one another according to their charges and show little
dotted lines to indicate the weak fleeting H-bonds between the molecules:
The polarity of water allows it to dissolve (pull apart) ions such as salts.
Draw a Na+ ion being dissolved (surrounded) by some water molecules (aligning the water
molecules properly):
Any type of ion or polar molecule that water is attracted to is described as HYDROPHILIC.
