1.	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» 1. 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. 2. Unsaturated solution: When minimum amount of solute is dissolved in a solvent at a given temperature and pressure is called an unsaturated solution. 3. 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 NaCI in 1 liter of water at 25°C. 2. An unsaturated solution has the capacity to dissolve more of the compound. 36 g of NaCI 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 NaCI in 1 liter of water at 25°C.
