Methyl orange is an indicator which will turn to yellow color in the presence of basic solution.

• Methyl orange is popularly used in titration to check the pH.
• Although its color scheme is not as diverse as the universal indicator, its endpoint is sharp which makes it an excellent choice for titration.
