Consider a mixture of soil and water and compare it to a colloid, such as milk. Which property best differentiates these two mixtures? A]Soil and water is a suspension because it consists of minute particles suspended in the medium. Milk is a colloid because it consists of larger particles suspended in the medium, which start to settle when allowed to stand. B]Soil and water is a colloid because it consists of minute particles suspended in the medium. Milk is a suspension because it consists of larger particles suspended in the medium, which start to settle when allowed to stand. C]Soil and water is a colloid because it has a uniform composition. Milk is a suspension because it doesn’t have a uniform composition. D]Soil and water is a suspension because it consists of larger particles suspended in the medium, which start to settle when allowed to stand. Milk is a colloid because it consists of minute particles that remain suspended in the medium. E]Soil and water is a suspension because it has a uniform composition. Milk is a colloid because it doesn’t have a uniform composition.

Answer:
suspension = particles in suspensions are larger than those found in solutions. can be evenly distributed by a mechanical means, like by shaking the contents, but the components will settle out. soil in water, blood, pond water, sea water, powdered chocolate milk, etc. colloid = particles intermediate in size (between those found in solutions and suspensions) can be mixed such that they remain evenly distributed without settling out. These particles range in size from 10^-8 to 10^-6 m in size and are termed colloidal particles or colloids. The mixture they form is called a colloidal dispersion. A colloidal dispersion consists of colloids in a dispersing medium. milk, gelletin (especially with fruit suspended in the solid jello), pudding, salad dressing (some) D A is out because colloid particles do NOT settle out B and C are out because they state that soil and water are colloidal E is out because colloids can be evenly distriubuted, and are, but will not settle out
