B. Sodium can be prepared by electrolysing fused NaCl
C. Sodium is a strong
agent
D. Sodium is soluble in liquid ammonia

Answer

To solve the question, we need to evaluate each of the given statements about sodium and determine which ones are correct. Let's go through each statement step by step.

### Step 1: Evaluate the first statement
**Statement:** Sodium can be prepared by electrolyzing aqueous solution of NaCl.

- **Analysis:** In an aqueous solution of NaCl, we have Na⁺ ions and H⁺ ions present. During electrolysis, the less reactive ion will be discharged at the electrode. Since H⁺ is less reactive than Na⁺, H⁺ will be discharged, leading to the production of hydrogen gas instead of sodium.
- **Conclusion:** This statement is **incorrect**.

### Step 2: Evaluate the second statement
**Statement:** Sodium can be prepared by electrolyzing fused NaCl.

- **Analysis:** In fused NaCl, only NaCl is present in a molten state, which means we have Na⁺ ions available for discharge at the electrode. Here, Na⁺ can be reduced to form sodium metal during electrolysis.
- **Conclusion:** This statement is **correct**.

### Step 3: Evaluate the third statement
**Statement:** Sodium is a strong agent.

- **Analysis:** The term "strong agent" is ambiguous without specifying whether it refers to a strong reducing agent or a strong oxidizing agent. Sodium has one electron in its outermost shell and tends to lose this electron easily, making it a strong reducing agent. However, due to its small size, it does not easily donate its electron, which suggests it is a weak reducing agent. Thus, calling sodium a "strong agent" is misleading.
- **Conclusion:** This statement is **incorrect**.

### Step 4: Evaluate the fourth statement
**Statement:** Sodium is soluble in liquid ammonia.

- **Analysis:** When sodium is dissolved in liquid ammonia, it reacts to form sodium amide (NaNH₂) and hydrogen gas (H₂). The presence of ammoniated electrons imparts a blue color to the solution, indicating that sodium is indeed soluble in liquid ammonia.
- **Conclusion:** This statement is **correct**.

### Final Conclusion
The correct statements are:
- **Statement 2:** Sodium can be prepared by electrolyzing fused NaCl.
- **Statement 4:** Sodium is soluble in liquid ammonia.

### Summary of Correct Statements:
- **Correct Statements:** 2 and 4.
