Mixtures

A mixture is a combination of two or more substances that are not chemically bonded and can be separated by physical means.

A heterogeneous mixture is a mixture in which the components are not uniformly distributed and can be easily distinguished, such as salad or dirt.

A homogeneous mixture is a mixture in which the components are uniformly distributed and cannot be easily distinguished, such as saltwater or glue.

An example of a heterogeneous mixture is chicken noodle soup, where you can see and separate the different ingredients.

An example of a homogeneous mixture is vinegar, where the components are evenly mixed.

Filtration is a method used to separate solids from liquids or gases using a filter medium that allows only the fluid to pass through.

Sand and water can be separated using a paper filter.

A solution is a type of homogeneous mixture where one substance is dissolved in another, while a mixture can be either homogeneous or heterogeneous.

An example of a mixture that is not easily separable is saltwater, as the salt is dissolved in the water.

The particle size in mixtures determines whether they are homogeneous or heterogeneous; larger particles often lead to heterogeneous mixtures.
