WATER_ CLASS 9

WATER Saturated, Unsaturated and Supersaturated Solution On the basis of solubility solutions are classified into three types: A solution that cannot dissolve anymore of the solute at a given temperature is called a saturated solution. A solution in which more solute can be dissolved is called an unsaturated solution. A solution in which more solute is present at a given temperature than in a saturated solution is called a supersaturated solution. E.g. The maximum amount of NaCl which can be dissolved in100g of water at 25 is 36g. So if a solution contains 36g of NaCl dissolved in 100g water then it is a saturated solution. If 10g NaCl is dissolved in 100g of water at 25 , it is an unsaturated solution. Now if we have a NaCl solution in which 50g of NaCl is dissolved in 100g of water at 25 then it is supersaturated solution. Solution: A solution is a homogeneous mixture of two or more components. The two components of the solutio...
