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.
Salt water and table salt +water are the same thing- a solution. Aluminum, gold and iron are all elements (pure substances) and can not be broken down. Jello is a colloid. Muddy water is a suspension, plus salad dressing. Perhaps sugar could be called a pure substance. But it can be broken down into its' component parts. Tea also.
it is a suspention
yes because salad dressing is a suspension of vinegar that will separate into layers if left undisturbed.
A true solution is a homogeneous mixture of at least two substances in which the solute has a particle size of less than 1 nm. Example: a simple solution of sugar in water. A colloidal solution is a heterogeneous mixture in which the suspension is between 1 and 1000 nm. Example: smoke from a fire.
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.
Suspension colliod :)
its a suspension. more specifially a colloid. emulsion.
Short answer: No. A salad dressing is specifically a colloid emulsion (when shaken/prepared), but easily becomes a suspension as the oil and water (in the vinegar) separate over time. On top of that, things like mustard seeds and herbs cause the dressing to become a mixture (as they could be filtered out). A salad in its entirety is a mixture, as the leaves are not dissolved in the dressing. So, salad cannot be a solution and neither is its dressing.
An example of a solution is salt water. An example of a suspension is Italian salad dressing. An example of a colloid is mayonnaise.

Suspension
Salad dressing contains some kind of oil mixed with vinegar, and these two substances are immiscible; they do not dissolve in each other, although if you mix them together you can get a suspension (which is temporary).
A salad is neither a suspension or a solution, it's a mixture.
vinaigrette
It is just a mixture. However, the salad dressing may be a suspension. For instance, Italian dressing is made using oil and vinegar which of course does not mix well.
