Green colour of universal indicator generally represents which solution?
Answer and explanation
Correct answer: Neutral solution
A universal indicator is a mixture of indicators that displays different colours over a range of pH values. Green is conventionally associated with a pH near 7, the neutral point of the scale. Thus, in the usual school interpretation, green indicates a neutral solution, making option B correct. Acidic solutions generally produce yellow, orange, or red shades, whereas strongly basic solutions tend toward blue or violet shades.
