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)
