Methyl orange is widely used as a pH indicator in various chemical and laboratory applications. It is particularly useful in titration experiments 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 reliable tool for identifying pH changes. It is commonly employed in educational laboratories to teach students about acid-base reactions and titration techniques. Additionally, it is used in some industrial processes to monitor pH levels in water treatment and chemical manufacturing. Its clear color transition makes it a practical choice for quick and accurate pH determination.
