Answer 2

Answer:

It is a heterogeneous mixture in which the solute particles do not dissolve but rather stay suspended, the particles are visible to the naked eye, the mixture may be filtered to remove the particles, and the particles scatter light.

Explanation:

Due to the presence of bigger particles suspended in the medium that begins to settle when left to stand, soil and water is a suspension. Due to the heterogeneous nature of the combination, the particles do not dissolve but rather remain suspended throughout most of the medium. A suspension's particles can be seen with bare eyes.

The chalk powder with water forms a suspension. When the solution is left undisturbed, the chalk particle gets settled down in the beaker.

When sugar is added to the water, it forms a saturated solution. Thus, sugar is completely dissolved in water and it does not remain in the beaker anymore. So it is not a suspension.

Fine sand has small particles which do not dissolve in water and get settled down at the bottom of the container. Thus, it forms a suspension with water.

Hence, A, B, and D are suspension.

The correct option is (a) A, B, and D are suspension.
