The biological signficance of water

Extracts from this document...


The Biological Significance of Water Water is the most available compound on earth. Many of us take it for granted. Although it is the basis of life, that is just the beginning of water as a useful chemical. In fact water is useful in more ways than most of us ever think about. Everyday chemists discover new uses for what is one of the things most taken for granted. Water still and holds new potential to change our world forever. Although water is abundant, it is a very simple compound with a complex set of properties. Nearly everything about water is somehow unusual or contradictory. Water has a formula of H2O which means it has two atoms of hydrogen and one of oxygen in every molecule. Water's melting and boiling points (Zero and 100 degrees Celsius respectively) are higher than would be expected based on similar compounds. It is unusually viscous based on its comparatively small molecular weight. Water has the ability to act as either an acid or a base depending on the circumstances, and by its nature it is perfectly neutral (it's the standard for balance between acids and alkalines[bases]). ...read more.


This is why water is ideal as insulation or a heat dissipation source. It holds more heat than just about anything. This is odd because there is nothing in its chemical makeup or structure that justifies this ability to hold so much heat. Water reacts with more substances than any other compound. It reacts physically with several compounds to add to their crystal structure. Compounds like copper and magnesium sulphate are two examples of many compounds that almost always found in nature with water molecules physically attached to their crystal structure. These types of compounds are often "dried out" or dehydrated and used to absorb water from their surroundings. Some of these compounds, have water as such an important part of their structure that they will even extract all available moisture from the air. These compounds are natural dehumidifiers, dependent on water to complete their structure. Water also reacts chemically with many substances, creating new substances or compounds. Dissolve Ammonia gas in water and the result is a powerful base, Ammonium Hydroxide. Dissolve Hydrogen Chloride gas in water and the result is a powerful acid, Hydrochloric Acid. ...read more.


It absorbs neutrons in nuclear power plants, yet is easily heated by microwaves. As abundant as water is and as familiar as it is, it is amazing what scientists can't explain about it. Why does it have such properties of cohesion? Water has a very high surface tension though it is such a small molecule. Why? What causes ice to expand as it gets colder? How can water act as both a polar and non-polar solvent? These and other questions have evaded complete explanation even today. Water still has some surprises left. Due to the existence of heavy hydrogen atoms of deutrium and trinium, water is the primary source of the raw materials needed for hydrogen bombs. Water also is the ideal source of hydrogen for the creation of Plasma, and the possible development of controlled fusion reactions. Water is a compound that we know so well yet know so little about. In its simple structure may be the key to understanding so much about the nature of chemical structures and reactions. A complete understanding of how and why the water molecule works may prove invaluable to our future development of new products and technologies. ?? ?? ?? ?? ...read more.

  1. Titration with a primary standard.

    At the end of each titration, record the value that is shown on the burette. When starting a new titration make sure that the volumetric flask that contained the sodium carbonate solution is fully rinsed out so that it does not mix with the new batch of sodium carbonate solution and therefore affect the result.

  2. Organic compound identification.

    Identity And Structure The unknown compound C is likely to be Butanal. Structure: Compound D Composition: C = 20.0% H = 6.7% hence E.F. = CH4N2O O = 26.7% N = 46.6% D is a natural compound formed as a product of the metabolism of proteins.
