Question

Can we separate chalk dust mixed in water by sedimentation and decantation? Why?

Answer 1

Answer:

yes we can seperate

Explanation:

Chalk is insoluble in water and forms a heterogeneous mixture when mixed with water. As chalk is heavier, therefore it will settle at the bottom of the mixture when it is left undisturbed for sometime. Thus, water can be separated from chalk powder by sedimentation, decantation and filtration.
