Question

How will you prepare a saturated solution of sodium chloride in water at 25°c what will happen if this solutions is cooled to 10°c

Answer 1

To prepare a saturated solution of nacl at 25°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.
