In a solution, methyl orange turns red and blue litmus turns red. What is the nature of the solution?
Answer and explanation
Correct answer: Acidic
Both indicator tests identify an acidic medium. Methyl orange turns red in an acidic solution, and acids turn blue litmus red because hydrogen or hydronium ions are present. Therefore the observations independently support option A. A basic solution would turn methyl orange yellow and blue litmus would remain blue, while a neutral solution would not produce either red change. Being a salt solution alone does not guarantee basicity.
