What colour does methyl orange become in an acidic solution?
Answer and explanation
Correct answer: Red
Methyl orange is an acid–base indicator whose colour depends on the acidity of the solution. In an acidic medium, it changes to red, so option C is correct. In a basic or alkaline medium it appears yellow, while blue and green are not the characteristic colours of methyl orange. Thus, the observation directly identifies the solution as acidic.
