Saturated solution: A solution that cannot dissolve any more solute in it is called a
               saturated solution.

               Unsaturated solution: An unsaturated solution is one which can dissolve more solute
               at a particular temperature.


               WATER- A UNIVERSAL SOLVENT

               Water is known as the Universal Solvent because it can dissolve a variety of different
               substances.

               This property of water is very important for every living organism on earth.
               Some important functions of water are:

                   (i)    Our body can absorb only that food which is dissolved in water.
                   (ii)   Water helps in transportation of digested food in our body.
                   (iii)   Water helps in transportation of vitamins and minerals in our body.
                   (iv)   Water helps to remove wastes and unnecessary wastes out of our body.
                   (v)    Plants take up vital nutrients, minerals, and salts from the soil through water.
                   (vi)   Aquatic plants and animals use dissolved oxygen and carbon dioxide for
                          sustaining life.


                   Thus, life would be impossible without water.
