Yes.
All colloids are suspensions but not all suspensions are colloids.
A colloidal suspension consists of particles small enough that they will not settle out of the material in which they are suspended.
Oil can be emulsified with a surfactant e.g., detergent to form an emulsion, a type of colloidal suspension. An example of this form of oil/water mixture is mayonnaise.
Homogenization of the butterfat (oil) in milk prevents the butterfat from layering out as you would see in un-homogenized (straight from the cow) milk.
Compare those two systems (mayonnaise and milk) to Italian dressing. No matter how hard or long you shake the bottle, in a short time the oil rises to the top. For a time, the oil was suspended but the droplet size never approached the size needed to form a colloid. See what happens if you put a drop of dishwashing detergent in the bottle of dressing before you shake it...but, don't put it on your salad.
Oil and vinegar form a heterogeneous mixture.
Paint is a type of colloid known as a sol, which is a solid dispersed in a liquid. The solid particles in paint, usually pigments and fillers, are dispersed in a liquid medium, such as water or oil, to form a stable mixture.
Oil-based paints tend to separate into layers over time. The pigment molecules are suspended in a solvent of linseed oil and mineral spirits. Oil-based paints are suspensions. Water-based paints such as latex paint are colloids.
Yes, soymilk is a colloid. It is an emulsion of oil droplets in water, where the oil phase is dispersed in the water phase. The particles in soymilk do not settle out over time, making it a colloidal solution.
Mayonnaise is a colloid, not a solution. In a solution, one substance dissolves completely in another, while in a colloid, small particles are dispersed but do not dissolve. Mayonnaise is made up of oil, water, egg yolks, and other ingredients that form an emulsion rather than a true solution.
colliod
suspension
Technically it could be any of those, depending on the type of cooking oil.
yes!
It is a colloid
Oil and vinegar dressing is a suspension because it consists of two immiscible liquids (oil and vinegar) that do not dissolve into each other. The vinegar forms droplets that are dispersed throughout the oil, creating a cloudy appearance.
It is a solution because if let sit over time particles will settle. ------------------------------------------------ Actually there is evidence with the related link below that shows it is a colloid
