What colour does methyl orange give in an acidic solution?
Answer and explanation
Correct answer: Red
Methyl orange is an acid-base indicator with a characteristic colour change over an acidic-to-basic pH range. In an acidic solution it appears red, while in a basic solution it appears yellow; during the transition it may show an intermediate orange shade. Since the question specifies an acidic medium, the expected colour is red. Yellow belongs to the basic condition, so option A is correct.
