The sharp pain caused by the sting of an ant is due to

Options

A. malic acid
B. nitric acid
C. formic acid
D. lactic acid

Explanation

**Step-by-Step Solution:**

1. **Identify the Cause of Pain**: The sharp pain caused by the sting of an ant is primarily due to the substances injected into the skin during the sting.

2. **Determine the Substance**: The substance responsible for the pain is a type of acid. In the case of ant stings, this acid is known as formic acid, which is also referred to as methanoic acid.

3. **Chemical Composition**: Formic acid has the chemical formula HCOOH. It is important to note that the video transcript incorrectly mentions the formula as FeOOH, which is not correct for formic acid.

4. **Effects of the Acid**: Upon being stung, the formic acid causes irritation and a burning sensation in the affected area, leading to sharp pain.

5. **Neutralization**: To alleviate the pain and irritation caused by the formic acid, a base such as sodium hydrogen carbonate (baking soda) is often applied. This base helps to neutralize the acid and reduce the discomfort.

6. **Conclusion**: Therefore, the sharp pain caused by the sting of an ant is due to the presence of formic acid.

**Final Answer**: The sharp pain caused by the sting of an ant is due to the presence of formic acid.
