Did You Know?
Methyl orange changes color over a narrow acidic pH range, shifting from red to yellow between pH 3.1 and 4.4. Because of this sharp transition, it has long been favored for strong acid–weak base titrations where precision is critical. Historically, methyl orange was one of the first synthetic dyes used as a chemical indicator, helping establish modern analytical chemistry techniques still taught today.
