Answer 2

Correspondence between dispersed systems and their classification:

1. Suspension: A suspension is a dispersed system in which solid particles are dispersed in a liquid or gas medium. The solid particles are usually larger and can settle down over time due to gravity. Examples of suspensions include muddy water, paint, and blood.

2. Emulsion: An emulsion is a dispersed system in which liquid droplets are dispersed in another immiscible liquid. The droplets are typically small and can be stabilized by emulsifiers. Examples of emulsions include milk, mayonnaise, and salad dressings.

3. True solution: A true solution is a dispersed system in which solute particles are uniformly dispersed at the molecular or ionic level in a solvent. The solute particles are typically very small and cannot be seen with the naked eye. Examples of true solutions include salt dissolved in water, sugar dissolved in tea, and alcohol dissolved in water.

4. Colloidal solution: A colloidal solution is a dispersed system in which small particles or droplets are dispersed in a continuous medium. The particles or droplets are larger than those in a true solution but smaller than those in a suspension. They can scatter light and exhibit the Tyndall effect. Examples of colloidal solutions include milk, gelatin, and fog.

Now let's match the dispersed systems with their classification:

1. Suspension - Г. Розчин кухонної солі у воді. [[1]] 2. Emulsion - Б. Суміш олії з водою. [[2]] 3. True solution - В. Суміш вапна з водою. [[3]] 4. Colloidal solution - А. Холодець. [[4]]

Please note that the provided examples are for illustrative purposes and may not cover all possible examples of each dispersed system.
