It is a colloid.


The particle size of a colloid are is very small, from #"10"-"1000 Angstroms"#. A colloid is cloudy and homogeneous in appearance and, unlike a suspension, the particles will not settle out. The scattering of light is called the Tyndall effect, in which the particles in the colloid reflect light, so that the beam of light will be visible.
