what is saturated solution how can one prepare a saturated solution of common salt in water
Answers
Answer:
Saturation specifies an equilibrium condition, that is poorly understood at even undergraduate level. By definition , a saturated solution contains an amount of solute that would be equal to that amount which would be in equilibrium with undissolved solute. An examiner would be quite justified in marking an answer that proposed that the ….
solvent holds all the solute that it can in a saturated solution
......….as incorrect...
And we could represent a saturated solution....
NaCl(s)H2O⇌Na++Cl−
We usually quote a temperature, because a hot solution can normally hold more solute than a cold one. In this scenario, the solubility of sodium chloride is rather insensitive to temperature.
And so get some water, approx. 100⋅mL, and add approx. 40−50⋅g of salt.... Not ALL of the salt will go up into solution...and here the equilibrium condition is satisfied... When the supernatant solution is decanted or filtered you gots the required saturated solution of NaCl(aq).

Adding sugar to water until it no longer dissolves creates a saturated solution. Continuing to dissolve salt in water until it will no longer dissolve creates a saturated solution. The Earth's soil is saturated with nitrogen. Mixing powdered soap into water until it will not dissolve creates a saturated solution.
a solution that cannot dissolve any more solute at a given temperature is called saturated solution.
take some water and add some salt in it and steer it.
again add some more salt and steer.
on this way go on dissolving salt.
a stage will come where no more salt will dissolve.
