Define the term solution. How many types of solutions are formed? Write briefly about each type with an example.
Hint :   Solution is the homogenous mixture of 2 or more components. Define and classify them on the basis of difference in their components.
 

Best Answer

A solution is a homogeneous mixture of two or more pure substances. It means their composition and properties are uniform throughout the solution. Solute and solvent are two components of a solution.
 
            Type of solutions : On the basis of different states of solute and solvent, solutions are of three types mainly, which are further categorized into three.
 
            These are listed in the following table with examples.
 
                  Types of solutions       Solute       Solvent           Examples
 
            1.   Gaseous solution        (a) Gas         Gas                 Mixture of oxygen and nitrogen gases.
 
                                                      (b) Liquid      Gas                 Chloroform mixed with nitrogen gas.
 
                                                      (c) Solid        Gas                 Camphor in nitrogen gas.
 
            2.   Liquid solutions           (a) Gas         Liquid               Oxygen dissolved in water.
 
                                                      (b) Liquid      Liquid              Ethanol dissolved in water.
 
                                                      (c) Solid        Liquid              Glucose dissolved in water.
 
            3.   Solid solutions            (a) Gas         Solid                Solution of hydrogen in palladium.
 
                                                      (b) Liquid      Solid                Amalgam of mercury with sodium.
 
                                                      (c) Solid        Solid                Copper dissolved in gold.
