$\huge\sf\pink{A}\blue{n}\purple{s}\red{w}\purple{e}\green{r :-}$

Explanation:

A colloid is just a mixture where a substance of dispersed insoluble particles is suspended throughout another substance. Chalk powder is very little soluble in water therefore this will form an suspension. ... Copper sulfate is very soluble in water, thereby making it a solution.

Answer 2

Answer:

chalk powder dissolved in water is an example of suspension.

Explanation:

colloids do not settle down when left undisturbed because it's quite stable. but when we dissolve chalk powder in water it does not dissolve completely because chalk comprises CaCO3 which is insoluble in water, the forces of attraction between calcium and carbonate ions are stronger than ions of calcium carbonate and water. The chalk powder settles down which can be seen by bare eyes easily. Therefore, chalk powder dissolved in water is an example of suspension.
