Olfactory indicators are substances whose odor changes in acidic or basic media. Unlike acid-base indicators, which change color, olfactory indicators rely on changes in smell to indicate the presence of acids or bases.

Olfactory indicators, unlike acid-base indicators, rely on the sense of smell for qualitative assessments. Olfactory indicators are substances with distinctive odors that change perceptibly in the presence of certain chemicals or specific environmental conditions. They are often used to detect the presence of substances such as gases, vapors, or volatile compounds. Acid-base indicators, on the other hand, visually signal pH changes through color shifts. While acid-base indicators are primarily employed in qualitative chemical analysis, olfactory indicators are utilized in applications where the sense of smell is crucial, such as in detecting gas leaks or identifying specific chemical reactions based on odor changes.
