The below mentioned article provides a brief account of structure, physical properties and importance of water to plant life. Structure of Water: Water (H2O) is normal oxide of hydrogen in which the two hydrogen atoms are joined to oxygen atom by covalent bonds forming an angle of 105° (Fig. 2.1 A). Since, oxygen atom is more electronegative than hydrogen atom; [...]
It is a common observation that when a little sugar or salt is dissolved in water, a homogeneous and stable mixture of the two components is obtained which is called as solution. Of these two components, the one (here sugar or the salt) which is present in small quantity is called as solute while the other (here water) present in [...]
