Answer

To solve the question regarding what should be rubbed on the stung area of the skin after an ant sting, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Cause of Pain**: When an ant stings a person, it injects a substance called formic acid into the skin. This acid is responsible for the burning pain that is felt.

2. **Identify the Nature of Formic Acid**: Formic acid is an acidic substance. Acids can cause irritation and pain when they come into contact with the skin.

3. **Determine the Required Substance for Relief**: To relieve the burning pain caused by an acid, we need to apply a basic substance. Bases can neutralize acids, which helps to alleviate the pain and discomfort.

4. **Evaluate the Options**:
- **Option 1**: Lemon juice - This is acidic in nature and will not provide relief.
- **Option 2**: Baking soda solution - This is basic in nature and can neutralize the formic acid, providing relief.
- **Option 3**: Vinegar - This contains acetic acid, which is also acidic and will not help in relieving the pain.
- **Option 4**: Sodium bicarbonate - This is another name for baking soda and is also basic.

5. **Select the Correct Answer**: The best option to rub on the stung area for relief is the baking soda solution (Option 2) because it is a basic substance that can neutralize the formic acid.

### Final Answer:
Rub baking soda solution on the stung area of the skin to get relief.
