Identify the correct statement

Options

A. Elemental sodium can be prepared and isolated by electrolysing an aqueous solution of sodium chloride
B. Element sodium is a strong oxidizing agent
C. Element sodium is insoluble in ammonia
D. Element sodium is easily oxidized

Answer

To identify the correct statement regarding sodium (Na), we will analyze each option provided in the question step by step.

### Step 1: Understanding Sodium
Sodium is a chemical element with the symbol Na. It is known for its properties and behavior in various chemical reactions.

### Step 2: Analyzing the Statements
We need to evaluate the given statements about sodium:

1. **Statement 1**: Sodium can be prepared and isolated by electrolyzing an aqueous solution of sodium chloride.
- **Evaluation**: This statement is true. Sodium can indeed be produced through the electrolysis of molten sodium chloride (NaCl).

2. **Statement 2**: Sodium is a strong oxidizing agent.
- **Evaluation**: This statement is false. Sodium is actually a strong reducing agent, not an oxidizing agent. It readily donates electrons in reactions.

3. **Statement 3**: Sodium is insoluble in ammonia.
- **Evaluation**: This statement is false. Sodium is soluble in ammonia, forming a blue solution.

4. **Statement 4**: Sodium is easily oxidized.
- **Evaluation**: This statement is true. Sodium is highly reactive and can be easily oxidized.

### Step 3: Conclusion
Based on the evaluations:
- **Correct Statements**: Statement 1 and Statement 4 are correct.
- **Incorrect Statements**: Statement 2 and Statement 3 are incorrect.

### Final Answer
The correct statements regarding sodium are:
- Sodium can be prepared and isolated by electrolyzing an aqueous solution of sodium chloride.
- Sodium is easily oxidized.
