Which acid is present in vinegar ?

Options

A. `CH_(3)`COOH
B. `H_(2)SO_(4)`
C. HCl
D. `"HNO"_(3)`

Answer

**Step-by-Step Solution:**

1. **Identify the Composition of Vinegar:**
- Vinegar is commonly known as a condiment and is primarily used in cooking and food preservation. The main component of vinegar is an acid.

2. **Determine the Type of Acid in Vinegar:**
- The acid present in vinegar is acetic acid. It is important to note that vinegar is essentially a diluted solution of acetic acid.

3. **Chemical Formula of Acetic Acid:**
- The chemical formula for acetic acid is CH₃COOH. This indicates that acetic acid contains two carbon atoms, four hydrogen atoms, and two oxygen atoms.

4. **Review the Options:**
- If provided with options, we need to identify which one corresponds to acetic acid (CH₃COOH).
- Common acids that might be listed include:
- Sulfuric acid (H₂SO₄)
- Hydrochloric acid (HCl)
- Nitric acid (HNO₃)
- Acetic acid (CH₃COOH)

5. **Select the Correct Option:**
- From the options, the one that matches the formula CH₃COOH is acetic acid. Therefore, the correct answer to the question "Which acid is present in vinegar?" is acetic acid.

**Final Answer:**
- The acid present in vinegar is acetic acid (CH₃COOH).
