Is Vinegar a mixture?
Vinegar is an example of a homogeneous mixture, and not a pure substance since water, its solute, is dissolved in the solvent, being acetic acid. … A homogenous mixture only consists of one phase, while a heterogeneous mixture is made up of 2+ phases.
Is milk a solution?
Milk is not a solution because it has more than one phase suspended in it — it has a liquid phase and a solid phase. Unhomogenized milk is not a solution, it’s a suspension because the fat (aka cream) will separate from the rest of the milk and rise to the top, since fat is less dense than water.
Is water and milk a colloid?
Milk is a colloid of fat particles in water. The fat particles in milk are not dissolved by water, but rather are suspended in the mixture. … No, milk cannot be dissolved in water – the resulting mixture is also a colloidal suspension.

Most toothpastes have abrasive particles to aid cleaning. Since the material is not homogeneous on the scale of the abrasive particles, it would be a nonhomogeneous mixture. Definitely a mixture.
Is Salt a mixture?
A pure substance consists of a single element or compound. Iron is formed only of iron (Fe) atoms; table salt is formed only by sodium chloride (NaCl) molecules. A mixture, however, is made up of different compounds and/or elements. When salt is added to water to make saltwater, it becomes a mixture.
Is blood a colloid or suspension?

Is salt water a colloid?
A solution is a homogenous mixture of two or more substances where one substance has dissolved the other. An example of a solution is saltwater . Colloids are homogenous mixtures where the particles are small enough that they stay suspended. An example of this is gelatin, which stays suspended in water to form a gel.
Is mayonnaise a solution suspension or colloid?
Mayonnaise is an emulsion colloid. Emulsions are a mixture of two liquids that can’t be combined, for instance, oil and water. Therefore, mayonnaise is made from the suspension of oil droplets in vinegar (a water-based continuous phase), stabilized by egg yolk molecules having both an oil-soluble and water-soluble end.
