Question

Consider a mixture of soil and water and compare it to a colloid, such as milk. Which property best differentiates these two mixtures? 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. 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. Soil and water is a colloid because it has a uniform composition. Milk is a suspension because it doesn’t have a uniform composition. 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. 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 1

I think the penultimate answer choice, "Milk is a colloid because it consists of minute particles that remain suspended in the medium," is the best one. The attached table is really handy to differentiate the two.

Answer 2

The correct answer is that 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.

Step-by-step explanation:

The particles present in suspensions are bigger in comparison to those witnessed in solutions. They can be distinguished evenly through mechanical means, like by shaking the constituents, as the components get settle down eventually.

While on the other hand, a colloid refers to a homogenous noncrystalline material comprising ultra-microscopic particles or big molecules of one substance dispersed via a second substance. The colloids comprise sols, gels, and emulsions.
