Answer

To solve the matching question, we will analyze each term from the first column and match it with the appropriate term from the second column based on the definitions and concepts related to solutions in chemistry.

### Step-by-Step Solution:

1. **Ideal Solution**:
- An ideal solution is one that follows Raoult's law perfectly. According to Raoult's law, the vapor pressure of a solution is directly proportional to the mole fraction of the solvent.
- **Match**: (i) "Ideal solution" → (g) "Raoult's law".

2. **Isotonic Solutions**:
- Isotonic solutions are solutions that have the same osmotic pressure. This means that when two solutions are separated by a semipermeable membrane, there will be no net movement of solvent.
- **Match**: (ii) "Isotonic solutions" → (f) "same osmotic pressure".

3. **Semipermeable Membrane**:
- A semipermeable membrane allows only certain particles to pass through, typically allowing solvent molecules to pass while blocking solute particles. This process is known as osmosis.
- **Match**: (iii) "Semipermeable membrane" → (a) "osmosis".

4. **Dissociation of Solute Molecules**:
- When a solute dissociates in solution, it produces more particles than were initially present. For example, NaCl dissociates into Na⁺ and Cl⁻ ions. This results in a van 't Hoff factor (i) greater than 1.
- **Match**: (iv) "Dissociation of solute molecules" → (b) "i > 1".

5. **Number of Solute Particles**:
- The number of solute particles affects colligative properties, such as relative lowering of vapor pressure. The more particles present, the greater the effect on the vapor pressure.
- **Match**: (v) "Number of solute particles" → (c) "Relative lowering of vapor pressure".

6. **Association of Solute Particles**:
- When solute particles associate, they form fewer particles in solution than were initially present. This results in a van 't Hoff factor (i) less than 1.
- **Match**: (vi) "Association of solute particles" → (d) "i < 1".

7. **Colligative Property**:
- Colligative properties depend on the number of solute particles in a solution and include effects like osmotic pressure and relative lowering of vapor pressure.
- **Match**: (vii) "Colligative property" → (e) "osmotic pressure".

### Final Matches:
- (i) "Ideal solution" → (g) "Raoult's law"
- (ii) "Isotonic solutions" → (f) "same osmotic pressure"
- (iii) "Semipermeable membrane" → (a) "osmosis"
- (iv) "Dissociation of solute molecules" → (b) "i > 1"
- (v) "Number of solute particles" → (c) "Relative lowering of vapor pressure"
- (vi) "Association of solute particles" → (d) "i < 1"
- (vii) "Colligative property" → (e) "osmotic pressure"
