What are colloids? Why is there no colloid inwhich both the disperse phase and dispersionmedium are gases? |
|
Answer» colloids are a homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle, and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.
An aerosol, sometimes called a liquid aerosol, is a liquid dispersed in agas, such as fog, which is tiny water droplets suspended in air. All gases are inherently miscible (completely soluble in each other), so by definitionthereisnosuch thing as agas-gas colloid |
