A colloid (also known as colloidal dispersion) may
look like a homogenous mixture, because the
mixture looks very uniform. Under a bit of
magnification, the solute is not completely dissolved,
and the particles are big enough, making the entire
For example—Mayonnaise is a mixture of egg yolk,
vinegar and lemon juice. It is whisked smoothly to
a degree that it feels so smooth, but under a
microscope, the solute is not completely dissolved.
Examples of colloids are Milk, Mayonnaise, Butter,
What is the difference between a colloid and an emulsion?
With colloids, the mixture has components that tend not to settle out when left

An emulsion is a uniform mix of two immiscible liquids (immiscible liquids are those
that do not dissolve well into each other)
