Question

differentiate between a saturated and a unsaturated solutions. how will you test whether a given solution is saturated or not ?​

Answer 1

➡Saturated solutions -In these solutions the addition of solute does not alter the equilobrium of the overall solution.i.e. we cannot add solute as it is not soluble further.

➡unsaturated solution-solute can be easily added to solution as it can further be mixed with solvent praticles.


Test whether a given solution is saturated or not...

➡By adding  cold dilute Baeyer's reagnant

More about Baeyer's Reagnant.

↪Baeyer's reagnant is cold dilute

↪It is an oxidising agent.

If this mixture is added to an unsaturated compounds such as alkenes or alkanes then :

Purple colour of  the reagnant changes .

It is first converted to a green compound   which is unstable in alkaline medium.

This again changes to brown  

The supernatant liquid gets decolourised.

However saturated compounds do not respond to the above test.

In simple words........... your answer is :

➡In order to test unsaturation first add cold dilute Baeyer's reagnant.

➡If the reagnant decolorises from purple to colourless then the compound is unsaturated

➡Otherwise if the reaction does not occur , then it is a saturated compound.
