How can hibiscus flower extract help in identifying acids and bases?
Answer and explanation
Correct answer: It can show colour change in different media
Hibiscus extract contains natural colour-producing substances that behave as an acid–base indicator. When the extract is added to an acidic medium and then to a basic medium, its colour can change differently, providing a visible clue about the solution. Thus, option A is correct. Options B, C and D are unrelated to indicator action and do not explain how acids or bases are identified.
