The separation of the constituents of the colloidal solution with the help of any separation process such as centrifugation, evaporation etc. is known as purification of colloids.
protective colloids are absorbed by solid particles,increase the strength of the double layer through hydrogen bonding and reduce the molecular interaction and aid in dispersion.they donot reduce the interfacial tension or the surface tension.
Colloids are heterogeneous mixtures because they contain dispersed particles that are not dissolved and are larger than those found in true solutions, giving them the appearance of being mixed yet not fully dissolved.
Examples of negatively charged colloids include silica sols, bentonite clay suspensions, and latex particles. These colloids have surfaces that are negatively charged due to the presence of ions or functional groups that attract and repel other particles in the dispersion medium.
Colloids scatter a beam of light that passes through them, exhibiting the Tyndall effect. This is due to the particles in colloids being large enough to obstruct the path of light and scatter it in all directions, making the beam visible.
ability of colloids is utilized in dyeing fabrics.
After my opinion they are not colloids.
These colloids are called emulsions.
some colloids cause pollution in the environment...some colloids release cfc's that contributes to the ozone layer depletion...
colloids are not visible due to their tiny particle size, (when the colloid is stable).
Yes, colloids can leave a residue when filtered. Colloids are larger particles that can be trapped by the filter, resulting in a residue left behind after filtration.
no
Frogs are not colloids, they are amphibians.
They are all colloids.they are all colloids
how are solutions suspensions and colloids alike

No, not all colloids have a negative charge. Colloids can have a positive, negative, or neutral charge depending on the type of particles present in the dispersion and the interactions between those particles.
