Mixtures
A mixture is a
combination of two or more elements or compounds in any proportion so
that the components do not lose their identity. Air is an example of a
mixture Mixtures are of two types, homogeneous and heterogeneous.
Homogeneous mixtures
have the same composition throughout the sample.
The components of such mixtures cannot be seen under a powerful
microscope. They are also called solutions. Examples of homogeneous
mixtures are air, seawater, gasoline, brass etc.
Heterogeneous mixtures
consist of two or more parts (phases), which have
different compositions. These mixtures have visible boundaries of
separation between the different constituents and can be seen with the
naked eye e.g., sand and salt, chalk powder in water etc.
