Colloids appear homogeneous to the naked eye, but under a microscope, the dispersed particles can be seen. They scatter light (Tyndall effect), unlike true solutions.Examples of colloids:Milk (liquid in liquid)Fog (liquid in gas)Gelatin (solid in liquid)Shaving cream (gas in liquid)
Answer:A colloid mixture is a type of mixture where tiny particles are spread out (dispersed) throughout another substance, but do not settle or separate over time. These particles are larger than those in a solution, but smaller than those in a suspension.Key Features:the mixture looks uniform, but the particles can be seen under a microscope. It doesn’t settle when left undisturbed. It can scatter light — this is called the Tyndall effect.Examples of Colloid Mixtures: Milk Mayonnaise Fog Gelatin Whipped creamSo, in simple terms, a colloid is a stable mixture where tiny particles are suspended and don't settle out easily.
