Methyl orange is widely used as a pH indicator in various chemical and biological applications. It is particularly useful in titrations to determine the acidity or alkalinity of a solution. In acidic conditions, it turns red, while in basic conditions, it changes to yellow, making it a valuable tool for identifying pH transitions in the range of 3.1 to 4.4. In educational laboratories, it is commonly employed to teach students about acid-base reactions and titration techniques. Additionally, it is used in environmental testing to assess the pH of water samples, ensuring water quality and safety. In industrial settings, methyl orange helps monitor chemical processes where pH control is critical, such as in wastewater treatment and manufacturing processes. Its clear color change provides a simple and effective way to detect pH shifts, making it a reliable indicator in both research and practical applications.
