Question

When a small amount of soil and pebbles are added to a beaker containing water and stirred well, it first forms a light brown liquid in which pebbles settle at the bottom. After half an hour, the soil is also observed to be settled at the bottom and the water above it appears clearer in the beaker. What conclusion can be made from this observation?

2 points

Both, soil and pebbles are soluble in water

Both, soil and pebbles are insoluble in water

Soil is insoluble in water, but pebbles are soluble

Pebbles are soluble in water and soil is insoluble

Explanation:

absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase – liquid or solid material. This is a different process from adsorption, since molecules undergoing absorption are taken up by the volume, not by the surface

Answer 2

Answer:

Both, soil and pebbles are insoluble in water

Explanation:

because soil and pebbles are insoluble
