Answer 2

Explanation:

THOSE SUBSTANCE WHOSE SMELL CHANGES IN ACIDIC OR BASIC SOLUTIONS ARE CALLED OLFACTORY INDICATORS.

HOWEVER GETTING BACK TO YOUR QUESTION YOUR IS AS FOLLOWS:-

ONION HAS A CHARACTERISTIC SMELL AND WE WILL ADD THE BASIC SOLUTION LIKE SODIUM HYDROXIDE TO A CLOTH STRIP TREATED WITH ONIONS ,THEN THE SMELL CANNOT BE DETECTED BY US.

BUT WHEN AN ACIDIC SOLUTION LIKE HYDROCHLORIC ACID IT DOES NOT DESTROY THE SMELL OF ONIONS.
