Simply put "a perminent distribution of the substance in the solvent". Colloids don't really form true solutions like sodium chloride does with water. Think of "Milk" as a great example. Water, Fats, and Proteins all get mixed together to make milk. The fats and proteins don't really get broken down, just kind of suspended in the mix.

What is colloidal dispersion?
When particles are suspended in a viscous (thick) mixture. Lots of oatmeal based lotions are colloidal.
What is natural dispersion?
Dense smoke from a forest fire - would disperse in the atmosphere. This would be an example of natural dispersion
What is the difference between Dispersion and Skewness?
distinguish between dispersion and skewness
What is dispersion and various measures of dispersion?
Dispersion is the act of spreading people or things (like seeds) out over a large area. Measures of dispersion tell us the degree of variation of values in a sample or population.
What is difference between absolute measure of dispersion and relative measures of dispersion?
The Absolute Measure of dispersion is basically the measure of variation from the mean such as standard deviation. On the other hand the relative measure of dispersion is basically the position of a certain variable with reference to or as compared with the other variables. Such as the percentiles or the z-score.
An emulsion is a colloidal dispersion of a?
gas in liquid
What kind of colloidal dispersion is a sol?
solid in a liquid

Can you separte a colloidal dispersion using a filter paper?
yes!
What is one property of skim milk indicating that it is a colloidal dispersion?
its dairy
Why do most colloids have electrical charges?
One of the most important properties of colloidal solutions is that colloidal particles posses a definite type of electrical charge. In a particular colloidal solution, all the colloidal particles carry the same type of charge, while the dispersion medium has an equal but opposite charge. Thus, the charge on colloidal particles is balanced by that of the dispersion medium and the colloidal solution as a whole is electrically neutral.
What is the scattering of a beam of visible light by the particles in a colloidal dispersion?
Tyndall effect
What is a mixture of solid and liquid which will separate if allowed to stand?
sand and water.
What is a substance with particles too large to dissolve called?
A colloid is a mixture in which one substance is divided into minute particles (called colloidal particles) and dispersed throughout a second substance. The mixture they form is called a colloidal dispersion. A colloidal dispersion consists of colloids in a dispersing medium. It doesn't have to be liquid.
What is an example of dispersion?
A rainbow is an example of dispersion noob
Is homogenized milk a compound or a mixture?
Homogenised milk is a homogeneous colloidal dispersion of the milk solids in the liquid milk. The colloidal particles are sized as per the requirements in high-speed colloidal mills. It is not a heterogeneous mixture.
