Mixtures are materials that contain two or more chemical substances dispersed among each other. A mixture shows the properties of its constituents. Depending on nature of components, mixture can be of two types:
It is a mixture in which the constituents are uniformly distributed, that is it has same composition throughout. E.g. salt dissolves in water to form a homogeneous mixture. Most homogeneous mixtures are called solutions like tea, coffee etc.
it is a mixture in which the constituents do not get mixed uniformly. E.g. sand and sawdust form a Heterogeneous mixture.
Mixtures can be categorized into various types, depending on the physical states of the constituents. Some of these types are discussed here.
