Vinegar contains

• A. $100\%$ acetic acid
• B. $10\%$ acetic acid dissolved in water
• C. $6\%-10\%$ acetic acid dissolved in water
• D. $15\%-20\%$ acetic acid dissolved in water

Answer 1

The correct option is C

$6\%-10\%$ acetic acid dissolved in water

The explanation for the correct option

(C) $\mathbf{6}\mathbf{\%}\mathbf{-}\mathbf{10}\mathbf{\%}$ acetic acid dissolved in water

Acetic acid

• Acetic acid is also known as ethanoic acid.
• It is a liquid having a chemical formula ${\mathrm{CH}}_3\mathrm{COOH}$.
• Vinegar gets its unique smell from acetic acid, a byproduct of fermentation.

Vinegar

• Vinegar is an aqueous solution of $6\%-10\%$ acetic acid $\left({\mathrm{CH}}_3\mathrm{COOH}\right)$ dissolved in water
• Acetic acid, the primary ingredient in vinegar, imparts a sour flavour and strong fragrance.
• Vinegar is a colourless solution of acetic acid in water produced by the fermentation of distilled alcohol.
• Vinegar has a pH of around $2.4$.

The explanation for incorrect options

• Vinegar contains $6\%-10\%$ acetic acid dissolved in water
• Hence, all other options (A), (B) and (D) are incorrect.

Therefore, the correct option is (C) $\mathbf{6}\mathbf{\%}\mathbf{-}\mathbf{10}\mathbf{\%}$ acetic acid dissolved in water.
