Question

Observe the given flowchart carefully and mark the appropriate option correctly representing I, II, and III.

• A. Sweet Calamine Formic acid
• B. Bitter Formic acid Baking soda
• C. Bitter Baking soda Calamine
• D. Sweet Formic acid Baking soda

Answer 1

Answer: (B)

Bitter Formic acid Baking soda

Acids are sour in taste and when ants bite they inject formic acid ($\text{HCOOH}$) into the victim. Hence $II$ is Formic acid.

This formic acid can be neutralized by a base. Baking soda is sodium bicarbonate which is alkaline in nature and can neutralize the formic acid. Hence $III$ is Baking soda.

It is bitter in taste ($I$).

Hence, option $B$ is correct.
