We will take hundred gram of distilled water in a beaker at 1 gram of NaCl and stirr with a glass rod till the NaCl dissolves. continue adding a gram of NaCl at a time and stirr vigorously after each adition. a stage will come when no more of the NaCl will dissolve at that temperature no matter how long it is left there are how vigorously it is stirred. if the temperature of a saturated solution is lowered the solvent slowly vaporizes and part of the dissolved solute separate out in the form of crystals.

To prepare a saturated solution of nacl at 30°C , we will have to take hundred grams of distilled water in a beaker at that temperature and add 1 gram of nacl at each time. Wr have to stirr the solutio until Nacl dissolves. We have to continue adding a gram of Nacl at a time until.a stage comes when no more Nacl dissolves. If the temperature is brought down to 10° C crystals of Nacl will appear as residue at the bottom of the beaker.
