description Product Description
Methyl Orange is widely used as a pH indicator in various chemical and biological applications. In titrations, it is particularly useful for determining the endpoint in acid-base reactions, especially in strong acid-strong base titrations. Its distinct color change from red in acidic solutions (pH below 3.1) to orange-yellow in alkaline solutions (pH above 4.4) makes it a reliable tool for pH monitoring. In educational laboratories, it is commonly employed to teach students about titration techniques and pH measurement. Additionally, it finds application in water treatment processes to monitor acidity levels and in industrial settings for quality control in chemical manufacturing. Its stability and ease of use make it a preferred choice for quick and accurate pH assessments.
