Question

How can be separated clay on chalk powder

Answer 1

Clay can be separated from the chalk powder by the process of Decantation.

Explanation:

• The given mixture is a heterogeneous mixture in which clay is high dense particle where chalk powder has low density.

• So, the clay particle settles down at the bottom and chalk powder float upon the water.

• Both of these now can be separated by the method of filtration using a filter paper.

• Decantation 'relies on gravity' to remove precipitate out from the solution'.

• So there is always some lack of product, either from the precipitate.

• Decanting is performed to segregate 'particulates from a liquid' by allowing the solids to settle to the bottom.

Answer 2

Decantation is the process through which the mixture of clay and chalk can be removed.

Explanation:

It is a process which is applied to separate 2 heterogeneous solution.

If a solution contain clay and chalk dust, then the clay will be precipitated in the water solution as their mol. wt is high but the chalk dust will be floating on the surface of water as the molecular weight is low.

Then by the process of filtration, the chalk dust is separated from the water solution.
