Homogeneous mixtures are types of mixtures in which components are present uniform throughout and we can not distinguish the components present in that mixture physically.
These particles do not show the Tyndall effect.
The constituent particles cannot be separated by using centrifugation or decantation.
Example: Soda water
Heterogeneous mixtures are types of mixtures in which components are not present uniform throughout.
The particles show a Tyndall effect.
Examples: starch solution, soap solution, and milk
