That means one example of a colloid mixture is fog. Colloid mixtures can be solid, liquid, or gas. Examples include butter, milk, and fog. There are actually 8 types of colloid mixtures.
Sometimes the dispersed substance alone is called the colloid; the term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the word suspension is contradistinguished from colloids by larger particle size).he dispersed-phase particles or droplets are affected largely by the surface chemistry present in the colloid. Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid. Other colloids may be opaque or have a slight color.
