Is milk an emulsion or suspension?
Milk is an emulsion, colloid suspension, or solution of various elements which is opaque and heterogeneous. Proteins, some minerals, and lactose along with some minerals and soluble proteins are all present in true solution, while fat exists in colloidal suspension as an emulsion.
Emulsion: Emulsions are combinations of two or more types of liquids, one of which is spread throughout the other as tiny or even ultrasmall droplets.
Suspension: A heterogeneous mixture called a suspension has some of its constituent particles, which, upon standing, separate from the mixture, Gravity can remove particles from the dispersion medium because suspension particles are much larger than solution particles (water).
Hence, milk is an emulsion, not a suspension.
