Methyl orange is yellow and turmeric is reddish-brown in a solution. What is the correct conclusion about this solution?
Answer and explanation
Correct answer: The solution is basic
Turmeric is a natural indicator that changes from yellow to reddish-brown in a basic medium. Methyl orange is yellow in a neutral or basic medium and becomes red in a sufficiently acidic medium. Therefore the two observed colours are consistent with an alkaline solution. The evidence does not support acidity, definite neutrality, or a gaseous state. Hence option B is the only appropriate conclusion.
