Is milk a colloid?

Hint: First let’s discuss what colloid is. So, a colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Milk is a colloid because it contains charged gap articles that remain suspended in the liquid.

Complete answer:
Milk is a colloid, with tiny globs of butterfat suspended throughout the liquid. Suspension is a mixture in which particles are dispersed throughout the bulk of a fluid. Milk is an emulsified colloid of Liquid is dispersed in liquid where liquid butterfat globules dispersed within a water-based solution
Milk appears to be a homogeneous mixture, it is a colloid because it has small globules of fat and protein that do not settle out after standing due to the (usually negatively) charged particles. These particles repel each other so they do not collect into larger particles that would settle out.
Other types of milk can vary in the amount of charged particles present.

Note:
Milk is a colloid of a liquid in liquid. Such colloids are called emulsion. In milk emulsion, liquid fat globules are dispersed in water. An emulsion is a mixture of two or more liquids that are normally immiscible i.e. unmixable or unblendable owing to liquid-liquid phase separation. Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably, emulsion should be used when both phases, dispersed and continuous, are liquids.
