- They are formed by mixing of 2 or more substances.
(these may be elements or compounds)
For example, Lemon Squash is made by mixing lemon juice, water and sugar.
The substances are
not chemically combined
in a mixture
For example, let us consider the water and sugar in the llemon squash. The molecules are merely present in the solution without forming bonds.
- A mixture shows properties of substances it is made up of
Example, sugar which is a sweet substance on being added to lemon juice makes it sweet.
Different Elements of mixtures can be
separated by Physical methods
(Example - Filtration, Sublimation, Evaporation etc.)
In this case, the seeds of the lemon can be separated by straining using a sieve
Example 1 -
If we put salt in water , it is a mixture
It does not form a new substance chemically.
It is possible to separate salt from water by using physical methods like evaporation.
Air is a mixture of different gases like Oxygen, Carbon Dioxide, Nitrogen etc.
It is possible to separate these different gases by using physical methods
