Question

Wht is saturated solution and how it is prepared

Answer 1

 A saturated solution is a solution which cannot contain any more dissolved solute, so to prepare a saturated solution of sugar water, you would slowly add sugar and stir until the solution reaches the point at which it cannot dissolve more solute and the sugar you add sinks to the bottom in solid form. This is a now saturated solution. 

Answer 2

hey mate,
here is your answer,
a saturated solution is one which has dissolved the maximum amount of a given molecule.
to prapare a saturated solution, you need to evaporate a solvent from a solution you have made until the solute begins to precipitate or crystallize.
hope it helps:-)
