A beaker contains a solution of substance 'A'. Precipitation of substance ‘A’ takes place when a small amount of 'A' is added to the solution. The solution is:
| 1. | Saturated. | 2. | Supersaturated. |
| 3. | Unsaturated. | 4. | Concentrated. |

Level 3: 35%-60%
Hints
The maximum amount of a solid solute that can be dissolved in a specified amount of a given liquid solvent does not depend upon:
| 1. | Temperature | 2. | Nature of solute |
| 3. | Pressure | 4. | Nature of solvent |

64%
Level 2: 60%+
Hints
Colligative properties are dependent on which of the following factors?
| 1. | The nature of the solute particles dissolved in the solution. |
| 2. | The number of solute particles in the solution. |
| 3. | The physical properties of the solute particles dissolved in the solution. |
| 4. | The nature of solvent particles. |

Level 1: 80%+
Hints
Relative lowering of vapor pressure is a colligative property because:
| (a) | It depends on the concentration of a non-electrolyte solute in a solution and does not depend on the nature of the solute molecules |
| (b) | It depends on the number of particles of electrolyte solute in a solution and does not depend on the nature of the solute particles |
| (c) | It depends on the concentration of a non-electrolyte solute in solution as well as on the nature of the solute molecules |
| (d) | It depends on the concentration of an electrolyte or non-electrolyte solute in solution as well as on the nature of solute molecules |
The correct choice among the given is:
1. (a, b)
2. (b, c)
3. (c, d)
4. (a, d)
