FURTHER EXPLANATION

A mixture is a physical combination of two or more elements or compounds. They share the same space or container only but do not mix chemically. Properties of individual components are retained and they can be obtained or retrieved by physical processes.

A homogeneous mixture is one in which the components are mixed uniformly so that it appears as if they exist in one phase. The individual components cannot be identified anymore because of the even distribution. If one were to take a sample of the mixture, the ratio of the components will be the same.

Cooking oil is an example of a homogeneous mixture. It is a combination of different refined oils. Each type of refined oil is no longer identifiable in a sample of cooking oil since they are mixed uniformly.

A heterogeneous mixture is a type of mixture wherein the individual components may still be identified. The components are not evenly and uniformly mixed so they remain distinguishable from each other. Each portion of the heterogeneous mixture may have a different ratio of the components in it. For example, a spoonful of vegetable soup may have 3 pieces of carrots, 2 onions and 1 celery. Getting another spoonful from the soup may not have the same number of carrots, onions, and celery again. The ratio of the components in a sample of the mixture is variable.
