Question

a solution when kept for sometime home to layer this solution can pass through the filter paper what types of solution it is it explain

Answer 1

If their is the formation of two layers, then we can say that solution is \textbf{suspension}suspension .

In such solutions actually the suspended particles settle down at the bottom, which leads to the formation of two different layers. 

Since, it's particles size ranges from 10^-5 cm or larger makes it not pass through the filter paper.
