Question

when a drop of dettol is added to 100ml water one can smell Dettol if 10 ml of the solution is taken in another beaker and for the deleted by adding 90ml one can still smell that all after deleting it for another two minutes like this the smallest state the physical nature of matter

Answer 1

Answer: As Dettol particles are very small in size there is more space in between them. This allows the Dettol particles to mix with water evenly.

This is the reason that in spite of repeated dilution the smell of Dettol remains in the solution and can be smelt.

This proves that only a small amount of solute dissolves in the particles that are too small.

Therefore adding more solute diffuses the air and the smell can be detected.
