Product Description:
m-Methyl red is widely used as a pH indicator in various laboratory settings. It is particularly useful in microbiology for differentiating bacterial species based on their metabolic activities. In the methyl red test, it helps identify bacteria that produce stable acids through glucose fermentation, turning red at low pH levels. Additionally, it is employed in titration experiments to determine the endpoint of acid-base reactions due to its distinct color change between pH 4.4 (red) and pH 6.2 (yellow). Its application extends to educational demonstrations, where it visually illustrates pH changes in chemical processes.
