What colour does universal indicator generally show in a neutral solution?
Answer and explanation
Correct answer: Green
A universal indicator is a mixture of indicators that displays different colours across the pH scale. A neutral aqueous solution has a pH close to 7, and the corresponding universal-indicator colour is generally green. Therefore option B is correct. Red and orange indicate acidic conditions, while violet represents a strongly basic region, not neutrality.
