Activity 2.2 | Smell the Science!

In Activity 2.2, we study olfactory indicators—substances whose smell changes in acidic or basic solutions.
Common olfactory indicators like onion, vanilla essence, and clove oil help us identify acids and bases when visual indicators fail.
When mixed with a base, the characteristic smell of these indicators disappears, while in an acidic medium, the smell remains unchanged.
This activity highlights the practical and everyday application of chemistry in an easy and interesting way.
Ideal for Class 10 Chemistry, NCERT practicals, and board exam preparation.
