               CHARACTERISTICS OF TRUE SOLUTIONS:
                   ➢  A solution is always clear and transparent.
                   ➢  The particles of solute in a solution are very small, i.e., in the order of the
                                         -9
                       order of 1 nm (10  metre).
                   ➢  A solution can completely pass through a filter.
                   ➢  A solution is homogeneous in nature.
                   ➢  In a solution, the particles of solute do not settle down, thus the solution is
                       stable in nature.
                   ➢  From a solution, the solute can be easily recovered by evaporation or
                       crystallisation.
                   ➢  Do not show Tyndall effect.


               CONCENTRATION OF SOLUTIONS:

               Concentration of a solution refers to the amount of solute dissolved in a given
               amount of solvent or solution at a particular temperature.


               Based on solute quantity, solutions can be dilute, concentrated, or saturated (when
               no more solute can dissolve at a given temperature).



               APPLICATIOBNS OF CONCENTRATION OF SOLUTIONS:

                       Formulating pharmaceutical dosage ( saline drips ).

                       Calculating food and beverage flavoring/ preservation.


                       Calculating stoichiometry in laboratories.

                       Monitoring environmental pollution levels.


                       Determining textile dye intensity.
