Water. From Biology, Campbell 5 th edition. Water ’ s polarity. A water molecule is shaped like a V, with two hydrogen atoms covalently bonded with an oxygen atom. The oxygen atom is more electronegative than the hydrogen.

Water molecules are electrically attracted to one another with the positive hydrogen ends of one molecule being attracted to the negative oxygen end of another water molecule.
This attraction results in a hydrogen bond.
Each water molecule can form hydrogen bonds to a maximum of four neighbors.
In the space below, draw a picture showing 3 water molecules. Indicate H and O atoms, their partial charges, and show where Hydrogen bonds would occur.
In the space below, list the three important properties of water we have learned so far….
The pH scale is used to measure the strength of acids and bases.
It ranges from 0-14, with pure water (7) as being neutral, and the lower the number the more acidic, and the higher the number the more basic.
