Which of the following salts with a concentration .1 M will give a basic solution ? (A)Ammonium acetate (B)Ammonium chloride (C)Ammonium sulphate (D)Sodium acetate

Options

A. Ammonium acetate
B. Ammonium chloride
C. Ammonium sulphate
D. Sodium acetate

Explanation

To determine which of the given salts will produce a basic solution when dissolved in water, we need to analyze the nature of each salt and the acids and bases from which they are derived.

### Step-by-Step Solution:

1. **Understanding the Types of Salts:**
- Salts can be classified based on the strength of the acids and bases from which they are formed:
- **Strong Acid + Strong Base** → Neutral Salt
- **Strong Acid + Weak Base** → Acidic Salt
- **Weak Acid + Strong Base** → Basic Salt
- **Weak Acid + Weak Base** → Neutral Salt

2. **Analyzing Each Option:**
- **(A) Ammonium Acetate (CH₃COONH₄):**
- Formed from acetic acid (weak acid) and ammonium hydroxide (weak base).
- Result: Neutral solution (neither basic nor acidic).

- **(B) Ammonium Chloride (NH₄Cl):**
- Formed from hydrochloric acid (strong acid) and ammonium hydroxide (weak base).
- Result: Acidic solution.

- **(C) Ammonium Sulfate ((NH₄)₂SO₄):**
- Formed from sulfuric acid (strong acid) and ammonium hydroxide (weak base).
- Result: Acidic solution.

- **(D) Sodium Acetate (CH₃COONa):**
- Formed from acetic acid (weak acid) and sodium hydroxide (strong base).
- Result: Basic solution.

3. **Conclusion:**
- Among the options, only **Sodium Acetate (D)** is formed from a weak acid and a strong base, which results in a basic solution.

### Final Answer:
**(D) Sodium Acetate**
