Question

Which of these is a constituent of vinegar?

• A. Acetic acid
• B. Sulphuric acid

Answer 1

The correct option is A

Acetic acid

Explanation for Correct option:

A. Vinegar is a liquid that is made when ethanol is fermented into acetic acid.

Acetic acid is a colorless liquid organic substance having the chemical formula $C{H}_{3}COOH$.

It is also known as Ethanoic acid. Apart from water, vinegar contains no less than 4% acetic acid by volume, making acetic acid the most important component.

Explanation for incorrect option:

B. Sulfuric acid is a mineral acid with a molecular formula of one sulphur ($S$) atom, four oxygen ($O$) atoms, and two hydrogen ($H$) atoms immediately bonded to two of the Oxygen atoms, forming the $-OH$ group, giving it the chemical formula $H_{2}S{O}_4$.

Therefore, Acetic acid is the constituent of vinegar.

So, the correct option is A.
