A student prepared three solutions : a solution of alum, soil and milk in water. Can you distinguish between the three on the basis of transparency and stability? Explain.

Heya friend,
Yes, we can distinguish between the three based on transparency and stability. Here is the answer-:
•Based on transparency-
> When alum is mixed in water, a true solution is formed which is totally TRANSPARENT and clear.
> When soil is mixed in water, a suspension is formed which is NOT CLEAR and dirty.
>When milk is mixed in water , a colloidal solution is formed, which is either translucent or opaque.
•Based on stability-:
> Alum and water solution is stable , as true solutions are stable.
>Soil and water solution is un-stable, as suspensions are not stable.The particle's settle down when left un-disturbed for some time.
>Milk and water solution is un-stable, as particles settle down if kept un-disturbed for a very long time otherwise they don't settle down.
Hope it helps...!!!
