A traditional example may be the litmus paper. When subjected to an acidic environment blue litmus paper turns red even though underneath simple disorders red litmus paper turns blue.
Indicators perform in chemical reactions by changing their properties, generally colour, in response to variations in the chemical ecosystem. This change is often due to the interaction concerning the indicator and also the hydrogen or hydroxide ions in the answer.
