What colour does methyl orange give in a basic solution?
Answer and explanation
Correct answer: Yellow
Methyl orange is an acid–base indicator whose colour depends on the acidity of the solution. It is red in an acidic medium and changes through an intermediate shade near its transition range, but it appears yellow in a basic or alkaline medium. Therefore, option B is correct. Blue and violet are not the standard alkaline colour of methyl orange, while red indicates an acidic medium.
