A mixture is made by mixing two or more different materials together. Note that there is no chemical combination in the constituents of a mixture. This means that constituents of a mixture can be separated by physical means. A mixture can be either homogeneous or heterogeneous, depending on the uniformity of mixing. If the different constituents of a mixture are uniformly present throughout, such a mixture is known as a homogeneous mixture.
A heterogeneous mixture consists of constituents which are not distributed uniformly throughout the mixture. A common solid based heterogeneous mixture is trail mix. This is made by mixing dry fruits, nuts, chocolates, grains, etc. The different components of trail mix are non-uniformly distributed in the mixture and can be easily separated into individual components. Note that each individual constituent retains its own properties (taste, color, etc.).
Some other examples of solid-based heterogeneous mixtures are
- a bowl of fruit loops
- a bowl of oatmeal and raisin cereal
- mixed nuts
Hope this helps.
