Mixtures: The substance having two or more elements or compounds that combine physically and not chemically.
There are two types of mixtures namely,
Homogeneous mixtures -
Those mixtures in which the substances are uniformly mixed without any clear boundary of separation are called homogeneous mixtures.
A homogeneous mixture has a uniform composition throughout its mass. In this type of mixture, the constituent particles cannot be seen with the naked eye.
A homogeneous mixture may be of solids, liquids, or gases.
Example: a Mixture of salt and sugar in water.
2. Heterogeneous mixtures -
Those mixtures in which the substances are non uniformly mixed with a clear boundary of separation are called heterogeneous mixtures.
A heterogeneous mixture has a non uniform composition throughout its mass.
In this type of mixture the constituent particles can be seen with the naked eye.
Example: A Mixture of sand and sugar, The Mixture of Petrol and Water.
