The properties of water that make it biologically important are its molecular polarity, thermal stability (elevated specific heat), fusion and boiling points that allow it to remain liquid in most environments, acid-base neutrality, small molecular size and low chemical reactivity.

Reactions, mechanism, synthesis, analysis, and biological function the study of organic chemistry, although complex, is very interesting, and begins here with an introduction of the theory of chemical bonding. Water quality parameters acidity or do, in water is expressed as a concentration a concentration is the amount of in weight of a particular substance per a given volume of liquid the do concentration in a stream is the mass of the oxygen gas present, in milligrams per liter of water it is one of the most important pollutants in the. 11 the importance of water water is one of the most important substances on earth all plants and animals must have water to survive if there was no water there would be no life on earth.

For most water systems, it is important to recognize the sources of alkalinity and maintain proper alkalinity control carbon dioxide dissolves in water as a gas the dissolved carbon dioxide reacts with solvent water molecules and forms carbonic acid according to the following reaction. Water in our bodies has many effects upon the ph it acts as a buffering substance, and it is required to remove toxic metals and toxic chemicals it is also required for millions of enzyme reactions needed to maintain health. Tap water is probably close to being neutral (ph 7), so we will use the two test papers that include ph 7 in their range ph 40-70 will be good if the water is somewhat acidic ph65-10 will be good if the water is somewhat alkaline.
