Which colour does universal indicator show in a neutral solution?
Answer and explanation
Correct answer: Green
A universal indicator is a mixture of indicators that displays different colours over a broad pH range. A neutral solution has a pH of approximately 7, and at this central point the standard colour shown by the universal indicator is green. Therefore option C is correct. Red generally corresponds to acidic conditions, while yellow is acidic to weakly acidic and violet indicates a strongly basic region.
