Colloids are particles of a certain size...around a micron to a fraction of a micron in diameter.
The key characteristic is mass/size...they are insoluble but form a suspension when added to a solvent...
That is to say they tend not to precipitate or form a deposit...they float...
gravitational forces are balanced by the physical properties of the solvent...
think of upthrust.
What else can I help you with?
Are colloids heterogeneous or homogeneous?
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.
Metal alloys belong to which type of colloid?
gel
What are the examples of negatively charged colloids?
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.
Which mixture scatter a beam of light that passes through them-a phenomenon called the Tyndall effect?
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.
The scattering of light by colloids is called?
the scattering of light by colloids is known as tyndall effect. it is named after the scientist who discovered it.
What are two components of colloids?
i don't know. even in my textbook theres none.

Are colloids heterogeneous or homogeneous?
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.
Is distillation used to separate by colloids?
No, distillation is not used to separate colloids. Distillation is a separation technique that is used to separate components of a liquid mixture based on differences in their boiling points. Colloids are mixtures where particles are dispersed throughout a medium but do not settle out, and they require other separation techniques such as filtration or centrifugation.
Are brownies colloids?
After my opinion they are not colloids.
How are liquid-liquid colloids like mayonnaise are called?
These colloids are called emulsions.
What are the negative effects of colloids on the environment?
some colloids cause pollution in the environment...some colloids release cfc's that contributes to the ozone layer depletion...
Metal alloys belong to which type of colloid?
gel
What is the visibility of colloids?
colloids are not visible due to their tiny particle size, (when the colloid is stable).
Mixtures that are not evenly mixed but cannot easily be separated by filtering -a -alloys-b-suspensions-colloids-d-solutions?
Colloids are mixtures where particles are dispersed but not dissolved in a medium, making them not evenly mixed but difficult to separate by filtering due to their small particle size. Alloys, mixtures of metals, can be evenly mixed but still difficult to separate due to their similar properties. Solutions are evenly mixed but can be separated if the components have different boiling points, while suspensions contain larger particles that can be separated by filtering.
When colloids are filtered do they leave residue?
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.
Is pizza a colloids?
no
