Explanation

To solve the problem of matching the salts in Column I with their corresponding pH characteristics in Column II, we need to analyze each salt based on the type of acid and base from which they are derived. Here’s a step-by-step breakdown:

### Step 1: Identify the salts and their components
- **(A) CH₃COONa**: This salt is formed from acetic acid (a weak acid) and sodium hydroxide (a strong base).
- **(B) NH₄Cl**: This salt is formed from hydrochloric acid (a strong acid) and ammonium hydroxide (a weak base).
- **(C) NaNO₃**: This salt is formed from nitric acid (a strong acid) and sodium hydroxide (a strong base).
- **(D) CH₃COONH₄**: This salt is formed from acetic acid (a weak acid) and ammonium hydroxide (a weak base).

### Step 2: Determine the pH characteristics of each salt
- **(A) CH₃COONa**: Since it is formed from a weak acid and a strong base, the solution will be basic. Therefore, it has a pH greater than 7.

- **(B) NH₄Cl**: This salt is formed from a strong acid and a weak base, resulting in an acidic solution. Hence, it has a pH less than 7.

- **(C) NaNO₃**: Being formed from a strong acid and a strong base, this salt will have a neutral pH of 7.

- **(D) CH₃COONH₄**: This salt is formed from a weak acid and a weak base, leading to a solution that is approximately neutral, but can be slightly above or below 7.

### Step 3: Match the salts with their corresponding pH characteristics
Now, we can match the salts from Column I with the appropriate descriptions from Column II:
- **(A) CH₃COONa** → (iii) "Alkaline" pH > 7
- **(B) NH₄Cl** → (ii) "Acidic" pH < 7
- **(C) NaNO₃** → (iv) "Neutral" pH = 7
- **(D) CH₃COONH₄** → (i) "Almost neutral" pH ≈ 7

### Final Matching
- (A) → (iii)
- (B) → (ii)
- (C) → (iv)
- (D) → (i)

### Conclusion
The correct matching of Column I with Column II is:
- **A → iii**
- **B → ii**
- **C → iv**
- **D → i**
