Explain the classification of matter based on chemical properties (macroscopic level).
(N/A) At the macroscopic or bulk level,matter can be classified as mixtures or pure substances. These can be further sub-divided as shown in the figure.
Many of the substances present around us are mixtures. For example,sugar solution in water,air,tea,etc.
$A$ mixture contains two or more substances present in it,which are called its components.
Pure substances have characteristics different from mixtures. They have a fixed composition,whereas mixtures may contain the components in any ratio and their composition is variable. Examples include copper,silver,gold,water,glucose,etc.
Glucose contains carbon,hydrogen,and oxygen in a fixed ratio and thus,like all other pure substances,has a fixed composition.
The constituents of pure substances cannot be separated by simple physical methods.
