The scattering of light by a colloidal dispersion is known as
A) an emulsion
B) an aerosol.
C) micelle repulsion.
D) Brownian motion.
E) Tyndall effect.

Question

Quizplus · Accepted Answer

The scattering of light by a colloidal dispersion is known as the Tyndall effect. This phenomenon occurs due to the particles in the colloidal dispersion being large enough to scatter light, causing the path of the light to become visible. Choice A (emulsion) refers to a mixture of two or more immiscible liquids. Choice B (aerosol) refers to a suspension of small particles in a gas. Choice C (micelle repulsion) refers to the repulsion between micelles (aggregates of surfactant molecules). Choice D (Brownian motion) refers to the random movement of particles in a fluid due to collisions with the molecules of the fluid.
