Instead, the two hydrogen ions are only 105 degrees apart, making that end of the molecule more positive than the other end, which is therefore more negative. These protective barriers of water molecules around the dissolved ions are called hydration sheaths. Be certain that you can draw the dipolar structure of the water molecule. See your notes for example. Some major dissolved ions in sea water are present in greater abundance than can be accounted for by the rate of delivery to the sea in river systems.
Chloride is perhaps the best example.
