What is saturated solution? Explain with an example

What is saturated solution? Explain with an example. 

Answer: 

A solution in which no more solute can be dissolved at any fixed temperature is called a saturated solution. In saturated solution, dissolved and undisolved solutes are in equilibrium with each 

other. 

Any more solute added will settle down at the bottom of the container as a precipitate. e.g. if 500 g of a solvent can dissolve a maximum of 150 g of a particular solute at 40°C. 

Then, the solution obtained by dissolving 150 g of that solute in 500 g of that solvent at 300 K is said to be a saturated solution at 300 K.
