What colour does universal indicator give 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 of approximately 7, and the standard universal-indicator colour for this condition is green. Therefore option B is correct. Red is associated with stronger acidity, while yellow generally indicates an acidic range and violet indicates a strongly basic range.
