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. |
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. |
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)
Colligative properties are observed when:
| (a) | A non-volatile solid is dissolved in a volatile liquid |
| (b) | A non-volatile liquid is dissolved in another volatile liquid |
| (c) | A gas is dissolved in a non-volatile liquid |
| (d) | A volatile liquid is dissolved in another volatile liquid |
1. (a, b)
2. (b, c)
3. (c, d)
4. (a, d)
Isotonic solutions must have the same:
| (a) | Solute |
| (b) | Density |
| (c) | Elevation in boiling point |
| (d) | Depression in freezing point |

2. (b, c)
3. (c, d)
4. (a, d)
| Type of solution | Example |
| a. Solid in gas | i. Aerated water |
| b. Gas in liquid | ii. Smoke |
| c. Liquid in solid | iii. Solution of hydrogen in palladium |
| d. Gas in solid | iv. Amalgams |

An example of a gas in a solid-type solution is:
1. Solution of hydrogen in palladium.
2. Ethanol dissolved in water.
3. Camphor vapours in N2 gas.
4. Amalgams.
