Answer

To solve the problem of matching the solutions in Column I with the corresponding colors in Column II, we can analyze each salt and its typical color in aqueous solution. Here’s a step-by-step solution:

### Step 1: Identify the color of FeSO₄·7H₂O
- **FeSO₄·7H₂O** (Iron(II) sulfate heptahydrate) typically exhibits a **green** color in solution.
- Match: **(i) FeSO₄·7H₂O → (d) Green**

### Step 2: Identify the color of NiCl₂·4H₂O
- **NiCl₂·4H₂O** (Nickel(II) chloride tetrahydrate) generally has a **pale green** color in solution.
- Match: **(ii) NiCl₂·4H₂O → (d) Pale green**

### Step 3: Identify the color of MnCl₂·4H₂O
- **MnCl₂·4H₂O** (Manganese(II) chloride tetrahydrate) usually appears as a **light pink** solution.
- Match: **(iii) MnCl₂·4H₂O → (b) Light pink**

### Step 4: Identify the color of CoCl₂·6H₂O
- **CoCl₂·6H₂O** (Cobalt(II) chloride hexahydrate) is known for its **pink** color in solution.
- Match: **(iv) CoCl₂·6H₂O → (e) Pink**

### Step 5: Identify the color of Cu₂Cl₂
- **Cu₂Cl₂** (Copper(I) chloride) is typically **colorless** in solution.
- Match: **(v) Cu₂Cl₂ → (f) Colourless**

### Final Matches
1. (i) FeSO₄·7H₂O → (d) Green
2. (ii) NiCl₂·4H₂O → (a) Pale green
3. (iii) MnCl₂·4H₂O → (b) Light pink
4. (iv) CoCl₂·6H₂O → (e) Pink
5. (v) Cu₂Cl₂ → (f) Colourless

### Summary of Matches
- (i) → (d)
- (ii) → (a)
- (iii) → (b)
- (iv) → (e)
- (v) → (f)
