Applications :
Microbiological Applications: Methyl Red Free Acid is utilized in microbiology, specifically in the identification of bacteria capable of performing mixed acid fermentation. It is used as a part of the Voges-Proskauer test, where the color change of the indicator indicates the presence of specific metabolic pathways in bacteria.Acid-Base Titration: Methyl Red Free Acid is often used as an indicator in acid-base titrations. Its pH-sensitive color change is employed to determine the endpoint of the titration reaction, enabling accurate measurements of the analyte concentration.pH Indicator:Methyl Red Free Acid is primarily used as a pH indicator. It exhibits a color transition from red in acidic solutions (pH < 4.4) to yellow in alkaline solutions (pH > 6.2). The transition range typically lies between pH 4.4 and 6.2. It is commonly employed in laboratory settings to monitor pH changes in chemical reactions or to determine the acidity or alkalinity of various solutions.Industrial Applications: Methyl Red Free Acid finds applications in various industrial processes. It is used in the production of dyes, pigments, and colorants for textiles, inks, and plastics due to its vibrant red color.Educational and Demonstration Purposes: Methyl Red Free Acid is commonly used in educational laboratories and demonstrations to teach pH concepts, acid-base chemistry, and the principles of chemical indicators. Its distinct color change and ease of use make it a valuable tool for visually illustrating pH changes in different solutions.
