• A. Salt
• B. Brine
• C. Tartar
• D. Vinegar

Hint:

The key ingredient that gives vinegar its characteristic sour taste and pungent smell is acetic acid. The typical concentration in household vinegar is around 5%.

Answer 1

The Correct Option is D

Step 1: Define the substance described. The question describes a solution of acetic acid with a concentration of 4%.
Step 2: Identify the common commercial name for this solution. Vinegar is, by definition, an aqueous solution of acetic acid. Commercial vinegar typically contains 4-7% acetic acid by volume, so a 4% solution fits this description perfectly.

Salt is sodium chloride.
Brine is a high-concentration solution of salt in water.
Tartar (cream of tartar) is potassium bitartrate. \end{itemize}
