Water covers about three fourths of the surface of the earth? It is also one of the simplest yet most important molecules in living systems.
It makes Bio water lab from 50 to 95 percent of the weight of living organisms. Polarity of Water Molecule The simplicity of the water molecule belies the complexity of its properties.
Based on its small size and light weight, one can predict how it should behave, yet it remains liquid at a much higher temperatures than expected. It also boils and freezes at much too high, or low, of a temperature for a molecule of its size.
Many of these unexpected properties of water are due to the fact that water molecules are attracted to each other like small magnets cohesion. This attraction results in turn from the structure of the water molecule and the characteristics of the atoms it contains. Each molecule of water is made up of two atoms of hydrogen connected to one atom of oxygen, as shown below.
This summarized in the familiar formula, H2O. Formation of a Water Molecule Hydrogen in water will take on a partial positive charge and why oxygen will take on a partial negative charge.
In this case, hydrogen bonding involves the attraction between the positively charged hydrogen atom of one water molecule and the negatively charged oxygen atom of another water molecule. As no electrons are actually shared however, hydrogen bonds are much weaker than covalent bonds — they easily break and easily form again.
Hydrogen Bonding in Water Water is everywhere. Water is an unusual substance with special properties. The properties of water help to answer several questions such as: Through a set of experiments, the unique properties of water and its consequent importance to living things will become apparent.Ultrapure is a leading provider of water treatment products and services for the laboratory market.

Water, H 2 O, is a polar molecule. The oxygen atom shares the pair of electrons with hydrogen in an unequal manner. Since oxygen is more electronegative than hydrogen, it has the tendency to pull the electrons towards itself more than hydrogen does.
