What colour does methyl orange indicator show in an acidic solution?
Answer and explanation
Correct answer: Red
The governing concept is the colour change of acid-base indicators. Methyl orange appears red in an acidic solution and changes through orange near its transition range to yellow in a sufficiently basic solution. Hence option B is correct. Yellow is associated with the basic-side colour, while blue and green are not the standard methyl-orange colour for an acidic solution. The indicator itself does not make the solution acidic; it only signals the existing pH range.
