Product Description:
Methyl red is widely used as a pH indicator in various laboratory settings. It is particularly useful in microbiology for the methyl red test, which helps differentiate between bacterial species based on their ability to produce stable acids through glucose fermentation. In analytical chemistry, it serves as a visual indicator in titrations to determine the endpoint of acid-base reactions, typically changing color from red at pH 4.4 and below to yellow at pH 6.2 and above. Additionally, it finds application in educational experiments to demonstrate pH changes and buffer solutions. Its stability and distinct color transition make it a reliable tool for monitoring pH levels in research and industrial processes.
