Which colour does universal indicator generally give in a neutral solution?
Answer and explanation
Correct answer: Green
A universal indicator is a mixture of indicators that shows different colours over a wide pH range. A neutral aqueous solution has a pH of about 7, and the indicator generally appears green at this central, neutral value. Therefore, option C is correct. Red usually represents an acidic solution, while blue or violet generally indicates a basic solution with a higher pH.
