Their application extends past chemistry into Personal computer science and environmental checking. Also, olfactory indicators include One more dimension by employing scent modifications to indicate chemical Houses, broadening the array of tools accessible for chemical Investigation.
Turmeric which we use inside our Way of life with the preparing of food stuff also can be used given that the chemical indicator. When utilized on an acidic medium it modifications its shade into yellow.
