You are provided with a solid 'A'and three solutions of A dissolved in water-one saturated, one unsaturated, and one super saturated. How would you determine each solution. |

Answer» Solution :(i) Saturated solution: When maximum amount of solute is dissolved in a solvent, any more addition of solute will result in precipitation at a given temperature and pressure. Such a solution is called a saturated solution. (ii) UNSATURATED solution: When minimum amount of solute is dissolved in a solvent at a given temperature and pressure is called an unsaturated solution. (iii) Super saturated solution: It is a solution that holds more solute than it normally could in its saturated form. Example 1. A saturated solution where the addition of more COMPOUND would not dissolve in the solution. 359 g of NaCl in 1 litre of water at `25^(@)C`. 2. An unsaturated solution has the capacity to dissolve more of the compound, 36 g of NaCl in 1 litre of water at `25^(@)C`. 3. A super saturated solution is the solution in which crystals can start growing, 500 g of NaCl in 1 litre of water at `25^(@)C`. |
