Properties of Water

Properties of water We use the word water everyday without thinking twice about what it is or why it¡¯s so important but without water life would seize to exist here on earth. Dihydrogen oxide, hydroxyl hydride, hydrogen hydroxide, are all chemical names for water none commonly used but all represents the single hydrogen and the two oxygen atoms. To gain an understanding of water you must first obtain an understanding of water¡¯s most important feature. This is the one feature that is responsible for nearly all of waters special qualities, hydrogen bonding. This single feature of water is what allows life to exist here on earth. This single feature is responsible for waters ability to float, its high specific heat and its cohesion. The hydrogen bond is a unique bond it is strong yet it is always breaking and reforming. The hydrogen bond allows water to form a higher level of structural organization then would be allowed in a molecule without hydrogen bonding. This is because water molecules can form hydrogen bonds with up to four neighbors and therefore allowing more structural organization. Hydrogen bonds are able to form because of the polarity of the water molecule. Oxygen is more electronegative then hydrogen and this results in the electrons of the polar bond spending more time closer to the oxygen atom. The result of this is the oxygen side of the molecule having a negative charge and the hydrogen side having a slight positive charge. Because the opposite ends have opposite charges water is considered to be a polar molecule and this results in the attraction between water molecules and the formation of hydrogen bonds. Hydrogen bonds are constantly breaking and reforming, the result of this it that at any given time a large amount of the water molecules are bonded to each other. This allows for a more structured shape then other liquids give, meaning that the water molecules are held together resulting in cohesion. In p...
