WATER AS OUR NATURAL RESOURSE There are more than 326 million trillion gallons of water on Earth. Less than 3 % of all this water is fresh water and of that amount‚ more than two-thirds is locked up in ice caps and glaciers. With so much water around it seems like there is enough to see us through for millions of years. But did you know that even water‚ which seems to be in abundance‚ might one day become scarce? Each time you throw something as garbage‚ think of where it will finally end up. Whether

The polarity of water Polarity means that the molecule has both a positively and negatively charged end. More important‚ the polarity of water is responsible for effectively dissolving other polar molecules‚ such as sugars and ionic compounds such as salt. Ionic compounds dissolve in water to form ions. This is important to remember because for most biological reactions to occur‚ the reactants must be dissolved in water. Because water is able to dissolve so many common substances‚ it is known as
