Question

why is a chalk powder solution referred as suspension​

Answer 1

Explanation:

The water (the substance) that passes through the filter paper is called the filtrate. If your mixture is a solution, such as salty water, then filtering will not separate the salt from the water. Instead, by heating the soluton the solvent (water) evaporates leaving the solid (salt) behind.

Answer 2

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
