Differences between Dispersed Systems and Examples of Mixtures

Dispersed systems and mixtures are both types of combinations of substances, but they have distinct characteristics. Let's explore the differences between dispersed systems and the examples of mixtures you provided:

A) Suspensions: 1) Milk is an example of a suspension. Suspensions are heterogeneous mixtures in which solid particles are dispersed in a liquid medium. In the case of milk, tiny fat globules are dispersed in water. When left undisturbed, the solid particles in a suspension tend to settle down due to gravity. However, they can be easily dispersed again by shaking or stirring the mixture [[1]].

B) Emulsions: 2) A solution of kitchen salt is not an example of an emulsion. Emulsions are a type of dispersed system in which two immiscible liquids, such as oil and water, are mixed together with the help of an emulsifying agent. The emulsifying agent stabilizes the mixture by preventing the separation of the two liquids. Examples of emulsions include mayonnaise and salad dressings, where oil and vinegar are mixed together with the help of egg yolk or mustard [[2]].

C) True Solutions: 3) Smoke is not an example of a true solution. True solutions are homogeneous mixtures in which the solute particles are uniformly dispersed at the molecular or ionic level in the solvent. The particles in a true solution are so small that they cannot be seen with the naked eye and do not settle down over time. Examples of true solutions include saltwater, sugar dissolved in water, and air [[3]].

D) Aerosols: 4) Mud in water is not an example of an aerosol. Aerosols are dispersed systems in which solid or liquid particles are dispersed in a gas medium. Examples of aerosols include fog, smoke, and spray paint. In the case of fog, tiny water droplets are dispersed in the air, creating a visible mist [[4]].

In summary, the main differences between dispersed systems and the examples of mixtures you provided are as follows: - Suspensions are heterogeneous mixtures with solid particles dispersed in a liquid medium. - Emulsions are mixtures of two immiscible liquids stabilized by an emulsifying agent. - True solutions are homogeneous mixtures with solute particles uniformly dispersed at the molecular or ionic level in the solvent. - Aerosols are dispersed systems with solid or liquid particles dispersed in a gas medium.
