Q. No.A beaker contains a solution of substance 'A' . Precipitation of substance ‘A’ takes place when small amount of 'A' is added to the solution. The solution is -
1. Saturated.
2. Supersaturated.
3. Unsaturated.
4. Concentrated.
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 |
Colligative properties depend on:
| 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)
Isotonic solutions must have the same-
a. Solute
b. Density
c. Elevation in boiling point
d. Depression in freezing point
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)
