Question

Vinegar is?

• A. Acidic re-agent
• B. Alkaline re-agent
• C. Greasy solvent
• D. Greasy absorbent

Answer 1

The Correct Option is A

To determine the nature of vinegar, we need to understand its chemical composition and properties.

Vinegar is primarily composed of acetic acid (CH₃COOH) and water. The presence of acetic acid is what gives vinegar its characteristic sour taste and acidic nature.

Now, let's evaluate the options given:

1. Acidic re-agent: This option is correct because vinegar contains acetic acid, making it an acidic substance.
2. Alkaline re-agent: This is incorrect because alkaline substances have a pH greater than 7, whereas vinegar, being acidic, has a pH less than 7.
3. Greasy solvent: This is incorrect as vinegar is a water-based solution and is not greasy. It acts more as a polar solvent due to its water content.
4. Greasy absorbent: This is incorrect for the same reason as above. Vinegar is not greasy and does not serve as an absorbent in the context meant by this option.

Thus, the correct answer is:

Acidic re-agent
